 *	After a read-write lock attributes object has been used to initialize
 *	one or more read-write locks, any function affecting the attributes object
 *	(including destruction) shall not affect any previously
 *	initialized read-write locks.
 * Steps:
 * 1.  Initialize a pthread_rwlockattr_t object with pthread_rwlockattr_init()i
 * 2.  Initialize two pthread_rwlock_t objects with this pthread_rwlockattr_t object
 * 3.  Destruct this pthread_rwlockattr_t objects.
 * 4.  The two pthread_rwlock_t objects should safely be used to lock and unlock.
