What operating system/version?
On our solaris system we never had any problems.
But on this linux system, with perl 5.6.1, linux 2.4.18, and libc 2.1.3,
the problem was pretty bad. (Mon was taking 2-3 minutes to start, or
process a reset request, because perl was spending so much time doing
memory mismanagement)

Don't take this wrong, but an argument could be made that perl -w doesn't
complain about superfluous problems, but complains about bad programming.
(using $foo{bar} when $foo{bar} doesn't exist in the hash, for example)
I've always liked the comment in the perl manpage about 'The -w switch is
not mandatory.' being a bug.
Regardless, I've got a version that -w is now pretty happy with. I think
I'm going to send my current patchset to you before I start working on the
per-host tracking stuff. Probably monday.
