   * Tests PTHREAD_MUTEX_RECURSIVE mutex type.
   * Thread locks mutex then trylocks mutex (recursive lock twice).
   * Both locks and unlocks should succeed.
   *
   * Depends on API functions: 
   *      pthread_create()
   *      pthread_join()
   *      pthread_mutexattr_init()
   *      pthread_mutexattr_destroy()
   *      pthread_mutexattr_settype()
   *      pthread_mutexattr_gettype()
   *      pthread_mutex_init()
   *      pthread_mutex_destroy()
   *	pthread_mutex_lock()
   *	pthread_mutex_unlock()
