  Merge new changes to unordered & hash.
  
   - Unordered tests can run lightweight test or Boost.Test (at least
     theoretically).
   - Workaround Open BSD's incorrect numeric_limits.
   - Move the hash extensions in their own file.
   - Various small improvements to the unordered docs.
   - Fix some unordered examples.

+# The boost threading library can be built on top of different API's
+# Currently this is the win32 API and the pthreads API.
+# Pthread is native on unix variants.
+# To get pthread on windows you need the pthread win32 library
+# http://sourceware.org/pthreads-win32 which is available under LGPL.
+#
+# You need to provide the include path and lib path in the variables
+# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
+# paths in site-config.jam, user-config.jam or in the environment.
+# A new feature is provided to request a specific API:
+# <threadapi>win32 and <threadapi)pthread.
+#
+# The naming of the resulting libraries is mostly the same for the
+# variant native to the build platform, i.e.
+# boost_thread and the boost specific tagging.
+# For the library variant that is not native on the build platform
+# an additional tag is applied:
+# boost_thread_pthread for the pthread variant on windows, and
+# boost_thread_win32 for the win32 variant (likely when built on cygwin).
+#
+# To request the pthread variant on windows, from boost root you would
+# say e.g:
+# bjam msvc-8.0 --with-thread install threadapi=pthread

+The original implementation of __boost_thread__ was written by William Kempf, with contributions from numerous others. This new
+version initially grew out of an attempt to rewrite __boost_thread__ to William Kempf's design with fresh code that could be
+released under the Boost Software License. However, as the C++ Standards committee have been actively discussing standardizing a
+thread library for C++, this library has evolved to reflect the proposals, whilst retaining as much backwards-compatibility as
+possible.
+
+Particular thanks must be given to Roland Schwarz, who contributed a lot of time and code to the original __boost_thread__ library,
+and who has been actively involved with the rewrite. The scheme for dividing the platform-specific implementations into separate
+directories was devised by Roland, and his input has contributed greatly to improving the quality of the current implementation.
+
+Thanks also must go to Peter Dimov, Howard Hinnant, Alexander Terekhov, Chris Thomasson and others for their comments on the
+implementation details of the code.

+
+A barrier is a simple concept. Also known as a ['rendezvous], it is a synchronization point between multiple threads. The barrier is
+configured for a particular number of threads (`n`), and as threads reach the barrier they must wait until all `n` threads have
+arrived. Once the `n`-th thread has reached the barrier, all the waiting threads can proceed, and the barrier is reset.

+[section:changes Changes since boost 1.34]
+
+Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface
+changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking
+changes are described below.
+
+[heading New Features]
+
+* Instances of __thread__ and of the various lock types are now movable.
+
+* Threads can be interrupted at __interruption_points__.
+
+* Condition variables can now be used with any type that implements the __lockable_concept__, through the use of
+`boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards
+compatibility). `boost::condition_variable` is provided as an optimization, and will only work with
+`boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`).
+
+* Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can
+be used as keys in associative containers, as they have the full set of comparison operators.
+
+* Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and
+with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only.
+
+* Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and
+`boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly
+available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types.
+
+[heading Breaking Changes]
+
+The list below should cover all changes to the public interface which break backwards compatibility.
+
+* __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`,
+but is no longer a separate class.
+
+* __recursive_try_mutex__ has been removed, and the functionality subsumed into
+__recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class.
+
+* `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work,
+as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member
+functions.
+
+* `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases,
+``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex,
+but did not lock it on construction. This facility has now been replaced with the constructor that takes a
+`boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);``
+
+* The broken `boost::read_write_mutex` has been replaced with __shared_mutex__.

-            linkend="threads.concepts.Mutex">Mutex</link> or one of its
-          refinements). The mutex object must be locked prior to waiting on the
-          condition, which is verified by passing a lock object (an object whose
-          type is a model of <link linkend="threads.concepts.Lock">Lock</link> or
-          one of its refinements) to the <classname>condition</classname> object's
-          wait functions. Upon blocking on the <classname>condition</classname>
-          object, the thread unlocks the mutex object. When the thread returns

-          functions the mutex object is again locked. The tricky unlock/lock

+[section:condvar_ref Condition Variables]
+
+[heading Synopsis]
+
+The classes `condition_variable` and `condition_variable_any` provide a
+mechanism for one thread to wait for notification from another thread that a
+particular condition has become true. The general usage pattern is that one
+thread locks a mutex and then calls `wait` on an instance of
+`condition_variable` or `condition_variable_any`. When the thread is woken from
+the wait, then it checks to see if the appropriate condition is now true, and
+continues if so. If the condition is not true, then the thread then calls `wait`
+again to resume waiting. In the simplest case, this condition is just a boolean
+variable:
+
+    boost::condition_variable cond;
+    boost::mutex mut;
+    bool data_ready;
+
+    void process_data();
+
+    void wait_for_data_to_process()
+    {
+        boost::unique_lock<boost::mutex> lock(mut);
+        while(!data_ready)
+        {
+            cond.wait(lock);
+        }
+        process_data();
+    }
+
+Notice that the `lock` is passed to `wait`: `wait` will atomically add the
+thread to the set of threads waiting on the condition variable, and unlock the
+mutex. When the thread is woken, the mutex will be locked again before the call
+to `wait` returns. This allows other threads to acquire the mutex in order to
+update the shared data, and ensures that the data associated with the condition
+is correctly synchronized.
+
+In the mean time, another thread sets the condition to `true`, and then calls
+either `notify_one` or `notify_all` on the condition variable to wake one
+waiting thread or all the waiting threads respectively.
+
+    void retrieve_data();
+    void prepare_data();
+
+    void prepare_data_for_processing()
+    {
+        retrieve_data();
+        prepare_data();
+        {
+            boost::lock_guard<boost::mutex> lock(mut);
+            data_ready=true;
+        }
+        cond.notify_one();
+    }
+
+Note that the same mutex is locked before the shared data is updated, but that
+the mutex does not have to be locked across the call to `notify_one`.
+
+This example uses an object of type `condition_variable`, but would work just as
+well with an object of type `condition_variable_any`: `condition_variable_any`
+is more general, and will work with any kind of lock or mutex, whereas
+`condition_variable` requires that the lock passed to `wait` is an instance of
+`boost::unique_lock<boost::mutex>`. This enables `condition_variable` to make
+optimizations in some cases, based on the knowledge of the mutex type;
+`condition_variable_any` typically has a more complex implementation than
+`condition_variable`.

-  <title>Design</title>
-  <para>With client/server and three-tier architectures becoming common place
-  in today's world, it's becoming increasingly important for programs to be
-  able to handle parallel processing. Modern day operating systems usually
-  provide some support for this through native thread APIs. Unfortunately,
-  writing portable code that makes use of parallel processing in C++ is made
-  very difficult by a lack of a standard interface for these native APIs.
-  Further, these APIs are almost universally C APIs and fail to take
-  advantage of C++'s strengths, or to address concepts unique to C++, such as
-  exceptions.</para>
-  <para>The &Boost.Threads; library is an attempt to define a portable interface
-  for writing parallel processes in C++.</para>

-    <title>Goals</title>
-    <para>The &Boost.Threads; library has several goals that should help to set
-	it apart from other solutions. These goals are listed in order of precedence
-	with full descriptions below.
-    <variablelist>
-	  <varlistentry>
-	    <term>Portability</term>
-		<listitem>
-          <para>&Boost.Threads; was designed to be highly portable. The goal is
-		  for the interface to be easily implemented on any platform that
-		  supports threads, and possibly even on platforms without native thread
-		  support.</para>

-	  </varlistentry>
-	  <varlistentry>
-        <term>Safety</term>
-        <listitem>
-          <para>&Boost.Threads; was designed to be as safe as possible. Writing
-		  <link linkend="threads.glossary.thread-safe">thread-safe</link>
-		  code is very difficult and successful libraries must strive to
-		  insulate the programmer from dangerous constructs as much as
-		  possible. This is accomplished in several ways:
-          <itemizedlist>
-            <listitem>
-              <para>C++ language features are used to make correct usage easy
-			  (if possible) and error-prone usage impossible or at least more
-			  difficult. For example, see the <link
-			  linkend="threads.concepts.Mutex">Mutex</link> and <link
-			  linkend="threads.concepts.Lock">Lock</link> designs, and note
-			  how they interact.</para>
-            </listitem>
-            <listitem>
-              <para>Certain traditional concurrent programming features are
-			  considered so error-prone that they are not provided at all. For
-			  example, see <xref linkend="threads.rationale.events" />.</para>
-            </listitem>
-            <listitem>
-              <para>Dangerous features, or features which may be misused, are
-              identified as such in the documentation to make users aware of
-              potential pitfalls.</para>
-            </listitem>
-          </itemizedlist></para>
-		</listitem>
-	  </varlistentry>
-      <varlistentry>
-	    <term>Flexibility</term>
-		<listitem>
-		  <para>&Boost.Threads; was designed to be flexible. This goal is often
-		  at odds with <emphasis>safety</emphasis>. When functionality might be
-		  compromised by the desire to keep the interface safe, &Boost.Threads;
-		  has been designed to provide the functionality, but to make it's use
-		  prohibitive for general use. In other words, the interfaces have been
-		  designed such that it's usually obvious when something is unsafe, and
-		  the documentation is written to explain why.</para>
-        </listitem>
-	  </varlistentry>
-      <varlistentry>
-        <term>Efficiency</term>
-		<listitem>
-          <para>&Boost.Threads; was designed to be as efficient as
-		  possible. When building a library on top of another library there is
-		  always a danger that the result will be so much slower than the
-		  "native" API that programmers are inclined to ignore the higher level
-		  API. &Boost.Threads; was designed to minimize the chances of this
-		  occurring. The interfaces have been crafted to allow an implementation
-		  the greatest chance of being as efficient as possible. This goal is
-		  often at odds with the goal for <emphasis>safety</emphasis>. Every
-		  effort was made to ensure efficient implementations, but when in
-		  conflict <emphasis>safety</emphasis> has always taken
-		  precedence.</para>
-        </listitem>
-	  </varlistentry>
-    </variablelist></para>
-  </section>
-  <section>
-    <title>Iterative Phases</title>
-    <para>Another goal of &Boost.Threads; was to take a dynamic, iterative
-	approach in its development. The computing industry is still exploring the
-	concepts of parallel programming. Most thread libraries supply only simple
-	primitive concepts for thread synchronization. These concepts are very
-	simple, but it is very difficult to use them safely or to provide formal
-	proofs for constructs built on top of them. There has been a lot of research
-	into other concepts, such as in "Communicating Sequential Processes."
-	&Boost.Threads; was designed in iterative steps, with each step providing 
-	the building blocks necessary for the next step and giving the researcher 
-	the tools necessary to explore new concepts in a portable manner.</para>
-    <para>Given the goal of following a dynamic, iterative approach
-	&Boost.Threads; shall go through several growth cycles. Each phase in its
-	development shall be roughly documented here.</para>
-  </section>
-  <section>
-    <title>Phase 1, Synchronization Primitives</title>
-    <para>Boost is all about providing high quality libraries with
-	implementations for many platforms. Unfortunately, there's a big problem
-	faced by developers wishing to supply such high quality libraries, namely
-	thread-safety. The C++ standard doesn't address threads at all, but real
-	world programs often make use of native threading support. A portable
-	library that doesn't address the issue of thread-safety is therefore not
-	much help to a programmer who wants to use the library in his multithreaded
-	application. So there's a very great need for portable primitives that will
-	allow the library developer to create <link
-	linkend="threads.glossary.thread-safe">thread-safe</link>
-	implementations. This need far out weighs the need for portable methods to
-	create and manage threads.</para>
-    <para>Because of this need, the first phase of &Boost.Threads; focuses
-	solely on providing portable primitive concepts for thread

-	  <answer>
-	    <para><emphasis role="bold">No!</emphasis> Lock objects are not meant to
-		be shared between threads. They are meant to be short-lived objects
-		created on automatic storage within a code block. Any other usage is
-		just likely to lead to errors and won't really be of actual benefit anyway.

-      <question>
-	    <para>Why was &Boost.Threads; modeled after (specific library
-		name)?</para>
-	  </question>
-	  <answer>
-	    <para>It wasn't. &Boost.Threads; was designed from scratch. Extensive
-		design discussions involved numerous people representing a wide range of
-		experience across many platforms. To ensure portability, the initial
-		implements were done in parallel using POSIX Threads and the Win32
-		threading API. But the &Boost.Threads; design is very much in the spirit
-		of C++, and thus doesn't model such C based APIs.</para>

-	  <question>
-	    <para>Why wasn't &Boost.Threads; modeled after (specific library
-	    name)?</para>
-	  </question>
-	  <answer>
-        <para>Existing C++ libraries either seemed dangerous (often failing to
-		take advantage of prior art to reduce errors) or had excessive
-		dependencies on library components unrelated to threading. Existing C
-		libraries couldn't meet our C++ requirements, and were also missing
-		certain features. For instance, the WIN32 thread API lacks condition
-		variables, even though these are critical for the important Monitor
-		pattern &cite.SchmidtStalRohnertBuschmann;.</para>

-	  <question>
-	    <para>Why do <link linkend="threads.concepts.mutexes">Mutexes</link>
-		have noncopyable semantics?</para>
-	  </question>
-	  <answer>
-        <para>To ensure that <link
-		linkend="threads.glossary.deadlock">deadlocks</link> don't occur. The
-		only logical form of copy would be to use some sort of shallow copy
-		semantics in which multiple mutex objects could refer to the same mutex
-		state. This means that if ObjA has a mutex object as part of its state
-		and ObjB is copy constructed from it, then when ObjB::foo() locks the
-		mutex it has effectively locked ObjA as well. This behavior can result
-		in deadlock. Other copy semantics result in similar problems (if you
-		think you can prove this to be wrong then supply us with an alternative
-		and we'll reconsider).</para>

-	  <question>
-	    <para>How can you prevent <link
-		linkend="threads.glossary.deadlock">deadlock</link> from occurring when
-		a thread must lock multiple mutexes?</para>
-	  </question>
-	  <answer>
-	    <para>Always lock them in the same order. One easy way of doing this is
-		to use each mutex's address to determine the order in which they are
-		locked. A future &Boost.Threads; concept may wrap this pattern up in a
-		reusable class.</para>

-	  </question>
-	  <answer>
-	    <para>No, but what it does mean is that the compiler can't generate a
-		copy constructor and assignment operator, so they will have to be coded
-		explicitly. This is a <emphasis role="bold">good thing</emphasis>,
-		however, since the compiler generated operations would not be <link

-	  </question>
-	  <answer>
-	    <para>The Monitor Pattern &cite.SchmidtStalRohnertBuschmann; mutex
-		should simply be declared as mutable. See the example code above. The
-		internal state of mutex types could have been made mutable, with all
-		lock calls made via const functions, but this does a poor job of
-		documenting the actual semantics (and in fact would be incorrect since
-		the logical state of a locked mutex clearly differs from the logical

-	  <answer>
-	    <para>There's a valid need for thread termination, so at some point
-		&Boost.Threads; probably will include it, but only after we can find a

-	    <para>Is it safe for threads to share automatic storage duration (stack)
-		objects via pointers or references?</para>
-	  </question>
-	  <answer>
-	    <para>Only if you can guarantee that the lifetime of the stack object
-		will not end while other threads might still access the object. Thus the
-		safest practice is to avoid sharing stack objects, particularly in
-		designs where threads are created and destroyed dynamically. Restrict
-		sharing of stack objects to simple designs with very clear and
-		unchanging function and thread lifetimes. (Suggested by Darryl
-		Green).</para>

-	    <para>Why has class semaphore disappeared?</para>

-			In the current Win32 implementation, creating a boost::thread object
-			during dll initialization will result in deadlock because the thread 
-			class constructor causes the current thread to wait on the thread that 
-			is being created until it signals that it has finished its initialization,

+[section:mutex_concepts Mutex Concepts]
+
+A mutex object facilitates protection against data races and allows thread-safe synchronization of data between threads. A thread
+obtains ownership of a mutex object by calling one of the lock functions and relinquishes ownership by calling the corresponding
+unlock function. Mutexes may be either recursive or non-recursive, and may grant simultaneous ownership to one or many
+threads. __boost_thread__ supplies recursive and non-recursive mutexes with exclusive ownership semantics, along with a shared
+ownership (multiple-reader / single-writer) mutex.
+
+__boost_thread__ supports four basic concepts for lockable objects: __lockable_concept_type__, __timed_lockable_concept_type__,
+__shared_lockable_concept_type__ and __upgrade_lockable_concept_type__. Each mutex type implements one or more of these concepts, as
+do the various lock types.
+
+[section:lockable `Lockable` Concept]
+
+The __lockable_concept__ models exclusive ownership. A type that implements the __lockable_concept__ shall provide the following
+member functions:
+
+* [lock_ref_link `void lock();`]
+* [try_lock_ref_link `bool try_lock();`]
+* [unlock_ref_link `void unlock();`]
+
+Lock ownership acquired through a call to __lock_ref__ or __try_lock_ref__ must be released through a call to __unlock_ref__.

+
+[section:shared_lockable `SharedLockable` Concept]
+
+The __shared_lockable_concept__ is a refinement of the __timed_lockable_concept__ that
+allows for ['shared ownership] as well as ['exclusive ownership]. This is the
+standard multiple-reader / single-write model: at most one thread can have
+exclusive ownership, and if any thread does have exclusive ownership, no other threads
+can have shared or exclusive ownership. Alternatively, many threads may have
+shared ownership.
+
+For a type to implement the __shared_lockable_concept__, as well as meeting the
+requirements of the __timed_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_shared_ref_link `void lock_shared();`]
+* [try_lock_shared_ref_link `bool try_lock_shared();`]
+* [unlock_shared_ref_link `bool unlock_shared();`]
+* [timed_lock_shared_ref_link `bool timed_lock_shared(boost::system_time const& abs_time);`]
+
+Lock ownership acquired through a call to __lock_shared_ref__, __try_lock_shared_ref__ or __timed_lock_shared_ref__ must be released
+through a call to __unlock_shared_ref__.

+
+
+[endsect]
+
+[section:upgrade_lockable `UpgradeLockable` Concept]
+
+The __upgrade_lockable_concept__ is a refinement of the __shared_lockable_concept__ that allows for ['upgradable ownership] as well
+as ['shared ownership] and ['exclusive ownership]. This is an extension to the multiple-reader / single-write model provided by the
+__shared_lockable_concept__: a single thread may have ['upgradable ownership] at the same time as others have ['shared
+ownership]. The thread with ['upgradable ownership] may at any time attempt to upgrade that ownership to ['exclusive ownership]. If
+no other threads have shared ownership, the upgrade is completed immediately, and the thread now has ['exclusive ownership], which
+must be relinquished by a call to __unlock_ref__, just as if it had been acquired by a call to __lock_ref__.
+
+If a thread with ['upgradable ownership] tries to upgrade whilst other threads have ['shared ownership], the attempt will fail and
+the thread will block until ['exclusive ownership] can be acquired.
+
+Ownership can also be ['downgraded] as well as ['upgraded]: exclusive ownership of an implementation of the
+__upgrade_lockable_concept__ can be downgraded to upgradable ownership or shared ownership, and upgradable ownership can be
+downgraded to plain shared ownership.
+
+For a type to implement the __upgrade_lockable_concept__, as well as meeting the
+requirements of the __shared_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_upgrade_ref_link `void lock_upgrade();`]
+* [unlock_upgrade_ref_link `bool unlock_upgrade();`]
+* [unlock_upgrade_and_lock_ref_link `void unlock_upgrade_and_lock();`]
+* [unlock_and_lock_upgrade_ref_link `void unlock_and_lock_upgrade();`]
+* [unlock_upgrade_and_lock_shared_ref_link `void unlock_upgrade_and_lock_shared();`]
+
+Lock ownership acquired through a call to __lock_upgrade_ref__ must be released through a call to __unlock_upgrade_ref__. If the

+
+__unique_lock__ is more complex than __lock_guard__: not only does it provide for RAII-style locking, it also allows for deferring
+acquiring the lock until the __lock_ref__ member function is called explicitly, or trying to acquire the lock in a non-blocking
+fashion, or with a timeout. Consequently, __unlock_ref__ is only called in the destructor if the lock object has locked the
+__lockable_concept_type__ object, or otherwise adopted a lock on the __lockable_concept_type__ object.
+
+Specializations of __unique_lock__ model the __timed_lockable_concept__ if the supplied __lockable_concept_type__ type itself models
+__timed_lockable_concept__ (e.g. `boost::unique_lock<boost::timed_mutex>`), or the __lockable_concept__ otherwise
+(e.g. `boost::unique_lock<boost::mutex>`). 
+
+An instance of __unique_lock__ is said to ['own] the lock state of a __lockable_concept_type__ `m` if __mutex_func_ref__ returns a
+pointer to `m` and __owns_lock_ref__ returns `true`. If an object that ['owns] the lock state of a __lockable_concept_type__ object
+is destroyed, then the destructor will invoke [unlock_ref_link `mutex()->unlock()`].
+
+The member functions of __unique_lock__ are not thread-safe. In particular, __unique_lock__ is intended to model the ownership of a
+__lockable_concept_type__ object by a particular thread, and the member functions that release ownership of the lock state
+(including the destructor) must be called by the same thread that acquired ownership of the lock state.

-    <title>Rationale for the Creation of &Boost.Threads;</title>
-    <para>Processes often have a degree of "potential parallelism" and it can
-	often be more intuitive to design systems with this in mind. Further, these
-	parallel processes can result in more responsive programs. The benefits for
-	multithreaded programming are quite well known to most modern programmers,
-	yet the C++ language doesn't directly support this concept.</para>
-    <para>Many platforms support multithreaded programming despite the fact that
-	the language doesn't support it. They do this through external libraries,
-	which are, unfortunately, platform specific. POSIX has tried to address this
-	problem through the standardization of a "pthread" library. However, this is
-	a standard only on POSIX platforms, so its portability is limited.</para>
-    <para>Another problem with POSIX and other platform specific thread
-	libraries is that they are almost universally C based libraries. This leaves
-	several C++ specific issues unresolved, such as what happens when an
-	exception is thrown in a thread. Further, there are some C++ concepts, such
-	as destructors, that can make usage much easier than what's available in a C
-	library.</para>
-    <para>What's truly needed is C++ language support for threads. However, the
-	C++ standards committee needs existing practice or a good proposal as a
-	starting point for adding this to the standard.</para>
-    <para>The &Boost.Threads; library was developed to provide a C++ developer
-	with a portable interface for writing multithreaded programs on numerous
-	platforms. There's a hope that the library can be the basis for a more
-	detailed proposal for the C++ standards committee to consider for inclusion
-	in the next C++ standard.</para>
-  </section>
-  <section id="threads.rationale.primitives">
-    <title>Rationale for the Low Level Primitives Supported in &Boost.Threads;</title>
-    <para>The &Boost.Threads; library supplies a set of low level primitives for
-	writing multithreaded programs, such as mutexes and condition variables. In
-	fact, the first release of &Boost.Threads; supports only these low level
-	primitives. However, computer science research has shown that use of these
-	primitives is difficult since it's difficult to mathematically prove that a
-	usage pattern is correct, meaning it doesn't result in race conditions or
-	deadlocks. There are several algebras (such as CSP, CCS and Join calculus)
-	that have been developed to help write provably correct parallel
-	processes. In order to prove the correctness these processes must be coded
-	using higher level abstractions. So why does &Boost.Threads; support the
-	lower level concepts?</para>
-    <para>The reason is simple: the higher level concepts need to be implemented
-	using at least some of the lower level concepts. So having portable lower
-	level concepts makes it easier to develop the higher level concepts and will
-	allow researchers to experiment with various techniques.</para>
-    <para>Beyond this theoretical application of higher level concepts, however,
-	the fact remains that many multithreaded programs are written using only the
-	lower level concepts, so they are useful in and of themselves, even if it's
-	hard to prove that their usage is correct. Since many users will be familiar

-    <title>Rationale for the Lock Design</title>
-    <para>Programmers who are used to multithreaded programming issues will
-	quickly note that the &Boost.Threads; design for mutex lock concepts is not
-	<link linkend="threads.glossary.thread-safe">thread-safe</link> (this is
-	clearly documented as well). At first this may seem like a serious design
-	flaw. Why have a multithreading primitive that's not thread-safe
-	itself?</para>
-    <para>A lock object is not a synchronization primitive. A lock object's sole
-	responsibility is to ensure that a mutex is both locked and unlocked in a
-	manner that won't result in the common error of locking a mutex and then
-	forgetting to unlock it. This means that instances of a lock object are only
-	going to be created, at least in theory, within block scope and won't be
-	shared between threads. Only the mutex objects will be created outside of
-	block scope and/or shared between threads. Though it's possible to create a
-	lock object outside of block scope and to share it between threads, to do so
-	would not be a typical usage (in fact, to do so would likely be an
-	error). Nor are there any cases when such usage would be required.</para>
-    <para>Lock objects must maintain some state information. In order to allow a
-	program to determine if a try_lock or timed_lock was successful the lock
-	object must retain state indicating the success or failure of the call made
-	in its constructor. If a lock object were to have such state and remain
-	thread-safe it would need to synchronize access to the state information
-	which would result in roughly doubling the time of most operations. Worse,
-	since checking the state can occur only by a call after construction, we'd
-	have a race condition if the lock object were shared between threads.</para>
-    <para>So, to avoid the overhead of synchronizing access to the state
-	information and to avoid the race condition, the &Boost.Threads; library
-	simply does nothing to make lock objects thread-safe. Instead, sharing a
-	lock object between threads results in undefined behavior. Since the only
-	proper usage of lock objects is within block scope this isn't a problem, and
-	so long as the lock object is properly used there's no danger of any
-	multithreading issues.</para>

-  <section id="threads.rationale.non-copyable">
-    <title>Rationale for NonCopyable Thread Type</title>
-    <para>Programmers who are used to C libraries for multithreaded programming
-	are likely to wonder why &Boost.Threads; uses a noncopyable design for
-	<classname>boost::thread</classname>. After all, the C thread types are
-	copyable, and you often have a need for copying them within user
-	code. However, careful comparison of C designs to C++ designs shows a flaw
-	in this logic.</para>
-    <para>All C types are copyable. It is, in fact, not possible to make a
-	noncopyable type in C. For this reason types that represent system resources
-	in C are often designed to behave very similarly to a pointer to dynamic
-	memory. There's an API for acquiring the resource and an API for releasing
-	the resource. For memory we have pointers as the type and alloc/free for
-	the acquisition and release APIs. For files we have FILE* as the type and
-	fopen/fclose for the acquisition and release APIs. You can freely copy
-	instances of the types but must manually manage the lifetime of the actual
-	resource through the acquisition and release APIs.</para>
-    <para>C++ designs recognize that the acquisition and release APIs are error
-	prone and try to eliminate possible errors by acquiring the resource in the
-	constructor and releasing it in the destructor. The best example of such a
-	design is the std::iostream set of classes which can represent the same
-	resource as the FILE* type in C. A file is opened in the std::fstream's
-	constructor and closed in its destructor. However, if an iostream were
-	copyable it could lead to a file being closed twice, an obvious error, so
-	the std::iostream types are noncopyable by design. This is the same design
-	used by boost::thread, which is a simple and easy to understand design
-	that's consistent with other C++ standard types.</para>
-    <para>During the design of boost::thread it was pointed out that it would be
-	possible to allow it to be a copyable type if some form of "reference
-	management" were used, such as ref-counting or ref-lists, and many argued
-	for a boost::thread_ref design instead. The reasoning was that copying
-	"thread" objects was a typical need in the C libraries, and so presumably
-	would be in the C++ libraries as well. It was also thought that
-	implementations could provide more efficient reference management than
-	wrappers (such as boost::shared_ptr) around a noncopyable thread
-	concept. Analysis of whether or not these arguments would hold true doesn't
-	appear to bear them out. To illustrate the analysis we'll first provide
-	pseudo-code illustrating the six typical usage patterns of a thread
-	object.</para>

-    <para>Of these usage patterns there's only one that requires reference
-	management (number 6). Hopefully it's fairly obvious that this usage pattern
-	simply won't occur as often as the other usage patterns. So there really
-	isn't a "typical need" for a thread concept, though there is some
-	need.</para>
-    <para>Since the need isn't typical we must use different criteria for
-	deciding on either a thread_ref or thread design. Possible criteria include
-	ease of use and performance. So let's analyze both of these
-	carefully.</para>
-    <para>With ease of use we can look at existing experience. The standard C++
-	objects that represent a system resource, such as std::iostream, are
-	noncopyable, so we know that C++ programmers must at least be experienced
-	with this design. Most C++ developers are also used to smart pointers such
-	as boost::shared_ptr, so we know they can at least adapt to a thread_ref
-	concept with little effort. So existing experience isn't going to lead us to
-	a choice.</para>
-    <para>The other thing we can look at is how difficult it is to use both
-	types for the six usage patterns above. If we find it overly difficult to
-	use a concept for any of the usage patterns there would be a good argument
-	for choosing the other design. So we'll code all six usage patterns using

-    <para>This shows the usage patterns being nearly identical in complexity for
-	both designs. The only actual added complexity occurs because of the use of
-	operator new in 
-	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>,
-	<link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link>, and
-	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>;
-	and the use of std::auto_ptr and boost::shared_ptr in 
-	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link> and 
-	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>
-	respectively. However, that's not really
-	much added complexity, and C++ programmers are used to using these idioms
-	anyway. Some may dislike the presence of operator new in user code, but
-	this can be eliminated by proper design of higher level concepts, such as
-	the boost::thread_group class that simplifies example 
-	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
-	down to:</para>
-    <programlisting>

-    }
-    </programlisting>
-    <para>So ease of use is really a wash and not much help in picking a
-	design.</para>
-    <para>So what about performance? Looking at the above code examples, 
-    we can analyze the theoretical impact to performance that both designs
-	have. For <link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>
-	we can see that platforms that don't have a ref-counted native
-	thread type (POSIX, for instance) will be impacted by a thread_ref
-	design. Even if the native thread type is ref-counted there may be an impact
-	if more state information has to be maintained for concepts foreign to the
-	native API, such as clean up stacks for Win32 implementations. 
-	For <link linkend="threads.rationale_comparison.non-copyable.joined">(2)</link>
-	and <link linkend="threads.rationale_comparison.non-copyable.loop">(3)</link>
-	the performance impact will be identical to
-	<link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>.
-	For <link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
-	things get a little more interesting and we find that theoretically at least
-	the thread_ref may perform faster since the thread design requires dynamic
-	memory allocation/deallocation. However, in practice there may be dynamic
-	allocation for the thread_ref design as well, it will just be hidden from
-	the user. As long as the implementation has to do dynamic allocations the
-	thread_ref loses again because of the reference management. For 
-	<link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link> we see
-	the same impact as we do for 
-	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>.
-	For <link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>
-	we still have a possible impact to
-	the thread design because of dynamic allocation but thread_ref no longer
-	suffers because of its reference management, and in fact, theoretically at
-	least, the thread_ref may do a better job of managing the references. All of
-	this indicates that thread wins for 
-	<link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>, 
-	<link linkend="threads.rationale_comparison.non-copyable.joined">(2)</link> and 
-	<link linkend="threads.rationale_comparison.non-copyable.loop">(3)</link>; with 
-	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
-	and <link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link> the
-	winner depending on the implementation and the platform but with the thread design
-	probably having a better chance; and with 
-	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link> 
-	it will again depend on the
-	implementation and platform but this time we favor thread_ref
-	slightly. Given all of this it's a narrow margin, but the thread design
-	prevails.</para>
-	<para>Given this analysis, and the fact that noncopyable objects for system
-	resources are the normal designs that C++ programmers are used to dealing

-	a different concept, and are not what is being discussed here.]</para>
-    <para>Event variables were one of the first synchronization primitives. They

-    <para>Per Brinch Hansen &cite.Hansen73; analyzed event variables in some
-	detail, pointing out [emphasis his] that "<emphasis>event operations force
-	the programmer to be aware of the relative speeds of the sending and
-	receiving processes</emphasis>". His summary:</para>
-    <blockquote>
-      <para>We must therefore conclude that event variables of the previous type
-	  are impractical for system design. <emphasis>The effect of an interaction

-	  carried out.</emphasis></para>
-    </blockquote>
-    <para>Experienced programmers using the Windows platform today report that
-	event variables are a continuing source of errors, even after previous bad
-	experiences caused them to be very careful in their use of event
-	variables. Overt problems can be avoided, for example, by teaming the event
-	variable with a mutex, but that may just convert a <link
-	linkend="threads.glossary.race-condition">race condition</link> into another
-	problem, such as excessive resource use. One of the most distressing aspects
-	of the experience reports is the claim that many defects are latent. That
-	is, the programs appear to work correctly, but contain hidden timing
-	dependencies which will cause them to fail when environmental factors or
-	usage patterns change, altering relative thread timings.</para>
-    <para>The decision to exclude event variables from &Boost.Threads; has been
-	surprising to some Windows programmers. They have written programs which
-	work using event variables, and wonder what the problem is. It seems similar
-	to the "goto considered harmful" controversy of 30 years ago. It isn't that
-	events, like gotos, can't be made to work, but rather that virtually all
-	programs using alternatives will be easier to write, debug, read, maintain,
-	and will be less likely to contain latent defects.</para>

-			<title>Statically-link build option added</title>
-
-			<para>The option to link &Boost.Threads; as a static
-			library has been added (with some limitations on Win32 platforms).
-			This feature was originally removed from an earlier version
-			of Boost because <classname>boost::thread_specific_ptr</classname>
-			required that &Boost.Threads; be dynamically linked in order
-			for its cleanup functionality to work on Win32 platforms.
-			Because this limitation never applied to non-Win32 platforms,
-			because significant progress has been made in removing
-			the limitation on Win32 platforms (many thanks to
-			Aaron LaFramboise and Roland Scwarz!), and because the lack
-			of static linking is one of the most common complaints of
-			&Boost.Threads; users, this decision was reversed.</para>
-			
-			<para>On non-Win32 platforms: 
-			To choose the dynamically linked version of &Boost.Threads; 
-			using Boost's auto-linking feature, #define BOOST_THREAD_USE_DLL;
-			to choose the statically linked version, 
-			#define BOOST_THREAD_USE_LIB. 
-			If neither symbols is #defined, the default will be chosen.
-			Currently the default is the statically linked version.</para>
-			
-			<para>On Win32 platforms using VC++: 
-			Use the same #defines as for non-Win32 platforms 
-			(BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB).
-			If neither is #defined, the default will be chosen. 
-			Currently the default is the statically linked version
-			if the VC++ run-time library is set to
-			"Multi-threaded" or "Multi-threaded Debug", and
-			the dynamically linked version
-			if the VC++ run-time library is set to 
-			"Multi-threaded DLL" or "Multi-threaded Debug DLL".</para>
-			
-			<para>On Win32 platforms using compilers other than VC++:
-			Use the same #defines as for non-Win32 platforms 
-			(BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB).
-			If neither is #defined, the default will be chosen. 
-			Currently the default is the dynamically linked version
-			because it has not yet been possible to implement automatic
-			tss cleanup in the statically linked version for compilers
-			other than VC++, although it is hoped that this will be
-			possible in a future version of &Boost.Threads;.
-			
-			Note for advanced users: &Boost.Threads; provides several "hook"
-			functions to allow users to experiment with the statically
-			linked version on Win32 with compilers other than VC++.
-			These functions are on_process_enter(), on_process_exit(),
-			on_thread_enter(), and on_thread_exit(), and are defined
-			in tls_hooks.cpp. See the comments in that file for more
-			information.</para>

-
-		<description>
-			<para>A <link linkend="threads.glossary.thread">thread of execution</link>
-			has an initial function. For the program's initial thread, the initial 
-			function is <code>main()</code>. For other threads, the initial 
-			function is <code>operator()</code> of the function object passed to
-			the <classname>thread</classname> object's constructor.</para>
-
-			<para>A thread of execution  is said to be &quot;finished&quot; 
-			or to have &quot;finished execution&quot; when its initial function returns or 
-			is terminated. This includes completion of all thread cleanup 
-			handlers, and completion of the normal C++ function return behaviors,
-			such as destruction of automatic storage (stack) objects and releasing 
-			any associated implementation resources.</para>
-
-			<para>A thread object has an associated state which is either
-			&quot;joinable&quot; or &quot;non-joinable&quot;.</para>
-
-			<para>Except as described below, the policy used by an implementation
-			of &Boost.Threads; to schedule transitions between thread states is 
-			unspecified.</para>
-
-			<para><note>Just as the lifetime of a file may be different from the
-			lifetime of an <code>iostream</code> object which represents the file, the lifetime
-			of a thread of execution may be different from the 
-			<classname>thread</classname> object which represents the thread of 
-			execution. In particular, after a call to <code>join()</code>,
-			the thread of execution will no longer exist even though the 
-			<classname>thread</classname> object continues to exist until the 
-			end of its normal lifetime. The converse is also possible; if 
-			a <classname>thread</classname> object is destroyed without 
-			<code>join()</code> first having been called, the thread of execution

+[section:thread_management Thread Management]
+
+[heading Synopsis]
+
+The __thread__ class is responsible for launching and managing threads. Each __thread__ object represents a single thread of execution,
+or __not_a_thread__, and at most one __thread__ object represents a given thread of execution: objects of type __thread__ are not
+copyable.
+
+Objects of type __thread__ are movable, however, so they can be stored in move-aware containers, and returned from functions. This
+allows the details of thread creation to be wrapped in a function.
+
+    boost::thread make_thread();
+
+    void f()
+    {
+        boost::thread some_thread=make_thread();
+        some_thread.join();
+    }
+
+[heading Launching threads]
+
+A new thread is launched by passing an object of a callable type that can be invoked with no parameters to the constructor. The
+object is then copied into internal storage, and invoked on the newly-created thread of execution. If the object must not (or
+cannot) be copied, then `boost::ref` can be used to pass in a reference to the function object. In this case, the user of
+__boost_thread__ must ensure that the referred-to object outlives the newly-created thread of execution.
+
+    struct callable
+    {
+        void operator()();
+    };
+
+    boost::thread copies_are_safe()
+    {
+        callable x;
+        return boost::thread(x);
+    } // x is destroyed, but the newly-created thread has a copy, so this is OK
+
+    boost::thread oops()
+    {
+        callable x;
+        return boost::thread(boost::ref(x));
+    } // x is destroyed, but the newly-created thread still has a reference
+      // this leads to undefined behaviour
+
+If you wish to construct an instance of __thread__ with a function or callable object that requires arguments to be supplied,
+this can be done using `boost::bind`:
+
+    void find_the_question(int the_answer);
+
+    boost::thread deep_thought_2(boost::bind(find_the_question,42));
+
+[heading Joining and detaching]
+
+When the __thread__ object that represents a thread of execution is destroyed the thread becomes ['detached]. Once a thread is
+detached, it will continue executing until the invocation of the function or callable object supplied on construction has completed,
+or the program is terminated. A thread can also be detached by explicitly invoking the __detach__ member function on the __thread__
+object. In this case, the __thread__ object ceases to represent the now-detached thread, and instead represents __not_a_thread__.
+
+In order to wait for a thread of execution to finish, the __join__ or __timed_join__ member functions of the __thread__ object must be
+used. __join__ will block the calling thread until the thread represented by the __thread__ object has completed. If the thread of
+execution represented by the __thread__ object has already completed, or the __thread__ object represents __not_a_thread__, then __join__
+returns immediately. __timed_join__ is similar, except that a call to __timed_join__ will also return if the thread being waited for
+does not complete when the specified time has elapsed.
+
+[heading Interruption]
+
+A running thread can be ['interrupted] by invoking the __interrupt__ member function of the corresponding __thread__ object. When the
+interrupted thread next executes one of the specified __interruption_points__ (or if it is currently __blocked__ whilst executing one)
+with interruption enabled, then a __thread_interrupted__ exception will be thrown in the interrupted thread. If not caught,
+this will cause the execution of the interrupted thread to terminate. As with any other exception, the stack will be unwound, and
+destructors for objects of automatic storage duration will be executed.
+
+If a thread wishes to avoid being interrupted, it can create an instance of __disable_interruption__. Objects of this class disable
+interruption for the thread that created them on construction, and restore the interruption state to whatever it was before on
+destruction:
+
+    void f()
+    {
+        // interruption enabled here
+        {
+            boost::this_thread::disable_interruption di;
+            // interruption disabled
+            {
+                boost::this_thread::disable_interruption di2;
+                // interruption still disabled
+            } // di2 destroyed, interruption state restored
+            // interruption still disabled
+        } // di destroyed, interruption state restored
+        // interruption now enabled
+    }
+
+The effects of an instance of __disable_interruption__ can be temporarily reversed by constructing an instance of
+__restore_interruption__, passing in the __disable_interruption__ object in question. This will
+restore the interruption state to what it was when the __disable_interruption__ object was constructed, and then
+disable interruption again when the __restore_interruption__ object is destroyed.
+
+    void g()
+    {
+        // interruption enabled here
+        {
+            boost::this_thread::disable_interruption di;
+            // interruption disabled
+            {
+                boost::this_thread::restore_interruption ri(di);
+                // interruption now enabled
+            } // ri destroyed, interruption disable again
+        } // di destroyed, interruption state restored
+        // interruption now enabled
+    }
+
+At any point, the interruption state for the current thread can be queried by calling __interruption_enabled__.
+
+[#interruption_points]
+
+[heading Predefined Interruption Points]
+
+The following functions are ['interruption points], which will throw __thread_interrupted__ if interruption is enabled for the
+current thread, and interruption is requested for the current thread:
+
+* [join_link `boost::thread::join()`]
+* [timed_join_link `boost::thread::timed_join()`]
+* [cond_wait_link `boost::condition_variable::wait()`]
+* [cond_timed_wait_link `boost::condition_variable::timed_wait()`]
+* [cond_any_wait_link `boost::condition_variable_any::wait()`]
+* [cond_any_timed_wait_link `boost::condition_variable_any::timed_wait()`]
+* [link thread.thread_management.thread.sleep `boost::thread::sleep()`]
+* __sleep__
+* __interruption_point__
+
+[heading Thread IDs]
+
+Objects of class __thread_id__ can be used to identify threads. Each running thread of execution has a unique ID obtainable
+from the corresponding __thread__ by calling the `get_id()` member function, or by calling `boost::this_thread::get_id()` from
+within the thread. Objects of class __thread_id__ can be copied, and used as keys in associative containers: the full range of
+comparison operators is provided. Thread IDs can also be written to an output stream using the stream insertion operator, though the
+output format is unspecified.
+
+Each instance of __thread_id__ either refers to some thread, or __not_a_thread__. Instances that refer to __not_a_thread__
+compare equal to each other, but not equal to any instances that refer to an actual thread of execution. The comparison operators on
+__thread_id__ yield a total order for every non-equal thread ID.

+[section Thread Local Storage]
+
+[heading Synopsis]
+
+Thread local storage allows multi-threaded applications to have a separate instance of a given data item for each thread. Where a
+single-threaded application would use static or global data, this could lead to contention, deadlock or data corruption in a
+multi-threaded application. One example is the C `errno` variable, used for storing the error code related to functions from the
+Standard C library. It is common practice (and required by POSIX) for compilers that support multi-threaded applications to provide
+a separate instance of `errno` for each thread, in order to avoid different threads competing to read or update the value.
+
+Though compilers often provide this facility in the form of extensions to the declaration syntax (such as `__declspec(thread)` or
+`__thread` annotations on `static` or namespace-scope variable declarations), such support is non-portable, and is often limited in
+some way, such as only supporting POD types.
+
+[heading Portable thread-local storage with `boost::thread_specific_ptr`]
+
+`boost::thread_specific_ptr` provides a portable mechanism for thread-local storage that works on all compilers supported by
+__boost_thread__. Each instance of `boost::thread_specific_ptr` represents a pointer to an object (such as `errno`) where each
+thread must have a distinct value. The value for the current thread can be obtained using the `get()` member function, or by using
+the `*` and `->` pointer deference operators. Initially the pointer has a value of `NULL` in each thread, but the value for the
+current thread can be set using the `reset()` member function.
+
+If the value of the pointer for the current thread is changed using `reset()`, then the previous value is destroyed by calling the
+cleanup routine. Alternatively, the stored value can be reset to `NULL` and the prior value returned by calling the `release()`
+member function, allowing the application to take back responsibility for destroying the object.
+
+[heading Cleanup at thread exit]
+
+When a thread exits, the objects associated with each `boost::thread_specific_ptr` instance are destroyed. By default, the object
+pointed to by a pointer `p` is destroyed by invoking `delete p`, but this can be overridden for a specific instance of
+`boost::thread_specific_ptr` by providing a cleanup routine to the constructor. In this case, the object is destroyed by invoking
+`func(p)` where `func` is the cleanup routine supplied to the constructor. The cleanup functions are called in an unspecified
+order. If a cleanup routine sets the value of associated with an instance of `boost::thread_specific_ptr` that has already been
+cleaned up, that value is added to the cleanup list. Cleanup finishes when there are no outstanding instances of
+`boost::thread_specific_ptr` with values.

-		<purpose>
-			<simpara>An object of type <classname>xtime</classname>
-			defines a time that is used to perform high-resolution time operations.
-			This is a temporary solution that will be replaced by a more robust time 
-			library once available in Boost.</simpara>
-		</purpose>
-
-		<description>
-			<simpara>The <classname>xtime</classname> type is used to represent a point on 
-			some time scale or a duration in time. This type may be proposed for the C standard by 
-			Markus Kuhn. &Boost.Threads; provides only a very minimal implementation of this
-			proposal; it is expected that a full implementation (or some other time
-			library) will be provided in Boost as a separate library, at which time &Boost.Threads;
-			will deprecate its own implementation.</simpara>
-			
-			<simpara><emphasis role="bold">Note</emphasis> that the resolution is 
-			implementation specific. For many implementations the best resolution 
-			of time is far more than one nanosecond, and even when the resolution 
-			is reasonably good, the latency of a call to <code>xtime_get()</code>
-			may be significant. For maximum portability, avoid durations of less than
-			one second.</simpara>

-// Change Log:
-//  10 Mar 02 
-//      Original version.
-//   4 May 04 GlassfordM
-//      Implement lock promotion and demotion.
-//      Add locked() and state() member functions for debugging
-//         (should these be made public?).
-//      Rename to improve consistency and eliminate abbreviations:
-//          Use "read" and "write" instead of "shared" and "exclusive".
-//          Change "rd" to "read", "wr" to "write", "rw" to "read_write".
-//      Add mutex_type typdef.

-// Change Log:
-//   6 Jun 01  
-//      WEKEMPF Initial version.
-//  30 May 02  WEKEMPF 
-//      Added interface to set specific cleanup handlers.
-//      Removed TLS slot limits from most implementations.
-//  22 Mar 04 GlassfordM for WEKEMPF
-//      Fixed: thread_specific_ptr::reset() doesn't check error returned
-//          by tss::set(); tss::set() now throws if it fails.
-//      Fixed: calling thread_specific_ptr::reset() or 
-//          thread_specific_ptr::release() causes double-delete: once on
-//          reset()/release() and once on ~thread_specific_ptr().
