This conceivably has a use, but NSS doesn't do this buffer either and it still
suffers from the same problems as the other uses of record_pqueue. This removes
the last use of record_pqueue. It also opens the door to removing pqueue
altogether as it isn't the right data structure for either of the remaining
uses either. (It's not clear it was right for record_pqueue either, but I don't
feel like digging into this code.)
