Postgres sense. I thought there was concern about multiple people trying to increment or decrement the count at the
sametime, and if that was the case perhaps there was an issue with it not being in a CRITICAL_SECTION as well. But I
couldcertainly be wrong about this. :)
And yes, we'd definitely not want to be in a CRITICAL_SECTION for the duration of the operation...
