Actually, according to my notes I had put off doing anything with this
because Hiroshi pointed out that CommandCounterIncrement had a shared-
cache-invalidation problem (it sent SI messages for changes that we
couldn't yet be sure would get committed).
Hiroshi's message last Monday stated that he'd fixed that problem,
so maybe now it's safe to start using CommandCounterIncrement more
heavily. Hiroshi, what do you think --- do you trust
CommandCounterIncrement now?
