* function that can be called from a thread creation routine
* (e.g., <pthread_create> or <_beginthreadex>) that expects an
* extern "C" entry point. This class also makes it possible to
* transparently provide hooks to register a thread with an
* <ACE_Thread_Manager>.
*
* This class is used in <ACE_OS::thr_create>. In general, the
* thread that creates an object of this class is different from
* the thread that calls <invoke> on this object. Therefore,
* the <invoke> method is responsible for deleting itself.
