Yes, but the "inc" is atomic at least on a UP system. So here "volatile"
might actually _show_ bugs instead of hiding them.

The real isssue, though, is that that is all volatile ever does. It can
show or hide bugs, but it can't fix them.

Of course, some people consider hidden bugs to _be_ fixed. I don't believe
in that particulat philosophy myself.
