Oops. This one is quite embarrassing:

However, you may find that tpop3d/auth-perl leaks memory
even with this installed. This is a consequence of perl's
crummy garbage collection, and there's nothing tpop3d can
do about it, except perhaps restart the embedded perl
interpreter every so often. I'm not sure how serious a
problem this is on production systems.
