* Test that pthread_exit()
*
* terminates the calling thread and makes the value 'value_ptr' available
* to any successful join with the terminating thread.
*
* Steps:
* 1. Create a new thread. Have it return a return code on pthread_exit();
* 2. Call pthread_join() in main(), and pass to it 'value_ptr'.
* 3. Check to see of the value_ptr and the value returned by pthread_exit() are the same;
