        I was browsing through my unread squid mail, and saw this
message, and it caught my interest, because I've also seen some FD
leakage for 1.NOVM.11, we're up to 656 FD's in use after 6 days. I
have to restart the server every week or so, as it runs out of FD's.
I'm fairly busy, so I don't have much time to document the issue, other
than to let the developers know that I'm seeing the problem, too..
(tho I'd be happy to help document the issue if someone wants to tell
me how.)
