 * Test pthread_exit()
 *
 * Any destructors for thread_specific data will be called when
 * pthread_exit is called
 *
 * Steps:
 * 1. Create a new thread.
 * 2. Create thread specific data, with a destructor in the thread
 * 3. Call pthread_exit in the thread.
 * 4. Make sure that the destructor was called
 *
