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.
