| * Test pthread_rwlock_init(). |
| * |
| * Once initialized, the lock can be used any number of times without being |
| * reinitialized. |
| * |
| * Steps: |
| * 1. Initialize a pthread_rwlock_t object 'rwlock' with pthread_rwlock_init() |
| * 2. Loop for COUNT time: lock for reading, unlock, lock for writing, unlock; |
