POSIX specifies that process-shared pthread_mutex_t's can be manipulated by independent processes, however the AMD64 and i386 versions of the mutex structures are incompatible and cannot be shared.
This might be true of the other supposedly sharable primitives, I never bothered to check the rest when I first noticed the problem with mutexes.
