 * Test that pthread_rwlock_rdlock(pthread_rwlock_t *rwlock)
 *
 *	A thread may hold multiple concurrent read locks on 'rwlock' and the application shall
 *	ensure that the thread will perform matching unlocks for each read lock.
 *
 * Steps:
 * 1.  Initialize a pthread_rwlock_t object 'rwlock' with pthread_rwlock_init()
 * 2.  Main read locks 'rwlock' 10 times
 * 3.  Main unlocks 'rwlock' 10 times.
