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:
http://en.wikipedia.org/wiki/Critical_section ?
If you mean in the postgres sense, you'd have to hold the critical
section open from the time you incremented the strong lock count all the
way until you decremented it (which is normally at the time the lock is
released); which is a cure worse than the disease.
