Logging mutex lock/unlock and destroy/free would show whether a locked
mutex is destroyed or freed, I think.

Another approach would be to add to pthread_mutex_destroy a check for
whether the mutex is locked, and make it crash. This would only catch
invalid destroy though, not free-without-destroy.
