    All right.  There's a good chance it is related to packet fragment
    handling or packetes related to dead connections.  But the more info
    we can get on the types of packets causing the problem the easier it 
    will be to track down.

    I think I see a bit of leak on my machines too now that you mention it.
    I'll try to track it down on my end as well.  Once we get it fixed I 
    think it's finally time for me to create a (non-branch) cvs tag to track
    known-to-be-probably-stable builds :-).
