JC, I am now starting to see the same behavior on python.org.  My
machine is slammed at 100% cpu almost continuously doing about the
same thing you're seeing.  I'd classify this as a problem that
requires a solution before 1.0 can go out.

I have no idea what's going on, or how to fix it, and as I mentioned
before I don't have the time right now to look into it.  But I just
wanted to say that it's a problem I have a vested interest in fixing
(although I'd be pleased as punch if someone else works on it in the
meantime :).
