pthread_mutex_lock is wrapped, I see no reason pthread_mutex_trylock shouldn't be too. In fact, it seems dangerous that it isn't.

Looks good!

By definition, http://linux.die.net/man/3/pthread_mutex_lock , pthread_mutex_trylock() has the same behavior as pthread_mutex_lock(), except pthread_mutex_trylock() could be EBUSY, but pthread_mutex_lock() does not, and pthread_mutex_lock() could be EDEADLK, but pthread_mutex_trylock() does not.  They are so similar, so to wrap pthread_mutex_trylock() with the same pattern of code seems very promise.
