Subject svn commit: r548119 - /incubator/stdcxx/trunk/tests/src/thread.cpp

	* thread.cpp [!_RWSTD_REENTRANT] (rw_thread_pool): When not reentrant
	 (in non-thread safe builds) emulated the creation of a single thread
	and then waiting for it to finish by simply calling the thread
	procedure to simplify the logic in each test.
