Coming back to shared memory mutexes etc, me personally if I want a mutex that is shared across processes and is resilient to sudden process death, I just lock a shared file in /tmp using flock().
Do you have any performance numbers of flock vs. e.g. futex? I would expect the former to be considerably slower.
