 [heading Default executor]

 The library authors share some of the concerns of the C++ standard committee (introduction of a new single shared resource, a singleton, could make it difficult to make it portable to all the environments) and that this library doesn't need to provide a default executor for the time been. 

-The user can always define his default executor himself and use the `at_thread_entry ` member function to set the default constructor.

 [*Sever limitations:]

 There are some severe bugs that prevent the use of the library on concrete contexts, in particular:

 * on thread specific storage that prevent the library to be used with dynamic libraries ( [@http://svn.boost.org/trac/boost/ticket/3926 #3926], ),
-* timed operation on windows are inconsistent ( [@http://svn.boost.org/trac/boost/ticket/9856 #9856], [@http://svn.boost.org/trac/boost/ticket/10967 #10967]).
-* The futures returned by async() and future::then() are not blocking ([@http://svn.boost.org/trac/boost/ticket/10968 #10968]).
