Unlikely. I think the real speedup comes if there are fewer spamd slaves
than MIMEDefang slaves.

Even embedded Perl doesn't help much, unfortunately. Perl uses a
reference-counting mechanism for garbage collection, which virtually ensures
that every page of memory gets written to, meaning slaves cannot share much
data. :-( It's a serious shortcoming of Perl.

Sure.
