Hence, didn't want to change it for CCI. We could use the batching
logic, if decide to do so. I can go ahead with that if there are no
other side effects with that.

We'll lose events regardless as our RMW sequence will race against the
counters. Batching will make that window slightly larger, but other than
that I don't see a problem.

OK, will do that.
