afaik mutexes have the same behaviour as binary semaphores that are used as mutexes (always locked and unlocked by the same process/thread):
".. the semaphore type can officially be considered to be on its way out. New code should not use semaphores, and old code which uses semaphores as mutexes should be converted over when an opportunity presents itself."
