 * Test that pthread_create() creates a new thread with attributes specified
 * by 'attr', within a process.
 *
 * Steps:
 * 1.  Create a thread using pthread_create()
 * 2.  Cancel that thread with pthread_cancel()
 * 3.  If that thread doesn't exist, then it pthread_cancel() will return
 *     an error code.  This would mean that pthread_create() did not create
 *     a thread successfully.
