I've just upgraded one of my servers from 4-10 to 4-20-3.  One of the
things I noticed is that the size in mem of MailScanner has almost
double!  Is this reasonable?

I've got most of the stuff that causes delays off (RBLS) but its slower
and doesn't clear out the queues nearly as fast.  I have a set of
scripts that tell me how many messages are sitting in each area
(incoming,, mqueue, and old queues). 4-10 is MUCH faster.
