SA is definitely (of course IMHO) one of the types of things that should
not use socket activation.  It is high overhead to start up (takes a
while to initialize), and things trying to use it that way could time
out.  The general expectation with SA is that if you want fast response,
use you spamd (started up at boot).  If you don't care about the
start-up time, you just use spamassassin directly.

Aside from that, I don't know if someone has set up socket activation
for anything in perl.  I guess it is using file descriptor passing?  I
haven't done that in perl before (although shouldn't be too hard).
