Do you need to put a memory barrier around that, or does the
critical section take care of that?
I used the interlocked increment/decrement, which- as I understand
it- should handle membar itself on architectures that can benefit
from it.
They do not include any memory barrier. The only thing those routines
guarantee on all platforms, is that the value is atomically
incremented/decremented.
