The book, Programming with POSIX Threads indicates that
pthread_mutex_destroy has the
following return values:
[EBUSY] mutex is in use.
[EINVAL] mutex is invalid.
Hint: Safets after unlocking mutex, when no other threads will lock.
Multithreaded Programmin with PThreads:
[EBUSY] Attempt to destroy a locked mutex.

Subject: destroying a locked mutex
Should pthread_mutex_destroy() return an error if the mutex is locked?
pthreads-win32 seems to disagree with the linux implementation of pthreads
on this point (OK on windows, not on linux).
