Dumb question... should operations in the various StrongLock functions

Do you mean CRITICAL_SECTION() in the postgres sense (that is, avoid
error paths by making all ERRORs into PANICs and preventing interrupts);
or the sense described here:
Postgres sense. I thought there was concern about multiple people trying to
increment or decrement the count at the same time, and if that was the case
perhaps there was an issue with it not being in a CRITICAL_SECTION as well. But
I could certainly be wrong about this. :)
And yes, we'd definitely not want to be in a CRITICAL_SECTION for the duration
of the operation...
