I have gotten a little further in my debugging - in one of the crashes
in addition to memory errors I got the processes complaining they were
running out of file handles; I've started MailScanner in shell with
ulimit -n 4096 and it seemed to plow through the queue.

No errors yet, I am waiting for the off-peak hours so I can do some load
testing. I intend to slam it with a few thousand messages and see if I
can replicate the issue.
