I don't see any problem here that urgently needs solving. If we ever
see any reports of out-of-memory failures in the bgwriter, then it'll
be time to worry about this, but I think it quite unlikely that we
ever will. (Even if we do, a simpler answer would be to increase
the initial size of the pending-requests hashtable.)
