I appear to have found a solution to my problem. I started running mon
under 'perl -w' to look for problems, and found *lots* of undefined values
being used. I've modified every one of them to have a defined $foo check
as well, and suddenly the memory footprint of my running mon system has
gone from 200M to 8M.
It's probably still a bug in perl that Mon was triggering by being careless
about undefined hash entries.
