I'm afraid this won't work. pthread_rwlock_init creates semaphores and

This static initialiser leaves the semaphore in an unusable state.
Oops. Hmm, looking at other implementations, the thing to do is to
check if "sem" is null on the first call to pthread_rwlock_*() and
initialize then. Does that sound correct?
