Ok, let's do this. I just need a few answers, and I'll prepare a patch:
an existing mutex or a new one? If an existing, then which one? If a new
one, then to what objects should it be added? Counters? Messages?

And, as I really want to understand it better, could you give some
rationale for "mutex vs. atomic"?
