mimedefang.pl is ~25MBish.  Our graphs are showing that we're not swapping
during these events, so I don't think that's the problem.

I've looked at it and am considering it, though we'd like to continue use
of spamd on this box for now with for the users (they get a *lot* of spam,
and their spamassassin settings are more aggressive than I'd like Mimedefang to
be).  Additionally, at this point I don't want to run AWL, Bayes or
Network tests in mimedefang, which said users need.

And to combine threads, as far as using tmpfs, that's an option, though
I'm seeing this on some smaller systems that are using tmpfs for teh
spooldir.  This makes me think that this is not the issue.
