Following up because I found a better way to debug this.

I'm now using Fazal Majid's awsome threadframe
(http://www.majid.info/mylos/stories/2004/06/10/threadframe.html) which
allows me to dump tracebacks of all python threads. I added a small hook
in ZServer.PubCore.ZRendezvous.ZRendezvous.handle to trigger the dump.

Now awaiting results...

PS: thanks to Maxime Yve from Unilog for making me discover threadframe.
