[[Note:] [The function passed to `call_once` must not also call
`call_once` passing the same `once_flag` object. This may cause
deadlock, or invoking the passed function a second time. The
alternative is to allow the second call to return immediately, but
that assumes the code knows it has been called recursively, and can
proceed even though the call to `call_once` didn't actually call the
function, in which case it could also avoid calling `call_once`
recursively.]]

[[Note:] [This function is *not* called if the thread was terminated
forcefully using platform-specific APIs, or if the thread is
terminated due to a call to `exit()`, `abort()` or
`std::terminate()`. In particular, returning from `main()` is
equivalent to call to `exit()`, so will not call any functions
registered with `at_thread_exit()`]]
