Yeah, the number reported by ps should be viewed with suspicion until
you know for certain whether it counts the shared memory segment or not.
(In my experience, on some platforms it does and on some it doesn't.)

However, I think the real issue here is probably just 6.5's well known
problems with intra-query memory leaks.  If Nigel can reproduce the
difficulty on 7.2 then I'd be more interested in looking into it...
