#. ---
#. Here is the relevant wording:
#. A thread may hold multiple concurrent read locks on rwlock (that is,
#. successfully call the pthread_rwlock_rdlock() function n times). If
#. so, the thread must perform matching unlocks (that is, it must call
#. the pthread_rwlock_unlock() function n times).
#. By making write-priority work correctly, I broke the above requirement,
#. because I had no clue that recursive read locks are permissible.
#. If a thread which holds a read lock tries to acquire another read lock,
#. and now one or more writers is waiting for a write lock, then the algorithm
#. will lead to an obvious deadlock. The reader will be suspended, waiting for
#. the writers to acquire and release the lock, and the writers will be
#. suspended waiting for every existing read lock to be released.
