Hi again,
Just noticed I skipped this question in your reply:
So in ReenterI() the OM_PERFDATA_OP(FutileWakeups, inc()) call
immediately
follows an OrderAccess::fence() call. Doesn't that make that
increment as
"safe" as it can be without having a real lock?
Yes - odd that I noticed the fence after the update in that code, and
not the one right before it!
That's because you didn't uncross your eyes before reading that part
of the monitor code... :-)

Thanks,
Tom
