I can't seem to duplicate it -- any processes I spawn don't seem to be
affected. (See below).

I have been trying to find any similarities by using exiwhat to see what
processes are hogging the RAM. They vary. Some are accepting inbound
connections, some are delivering email. None of the email deliveries or
inbounds that I was able to trace down were bigger than 15Kb, and nothing
abnormal looking in the headers.

This, I will try.
To update my situation: I have managed to stabalize the mail system
enough that it doesn't crash. I've got just the right combination of
load-limiting options that seem to keep it going.
