Sorry, it's just that I _really_ hate this patch. We're making up
a weird locking primitive that tracks the process, with a weird
unlock helper that only unlocks if it's the process that is
holding the mutex.

I'll try and think about this a bit, it would be nice if we had
a better alternative than the above.
