Do you need to put a memory barrier around that, or does the critical
section take care of that?

guarantee on all platforms, is that the value is atomically
incremented/decremented.

Is there a preferred way of reading back whether something (including
the current thread) has already entered a TCriticalSection?
I'm trying to put assertions in code that, partly under non-GUI thread
