Yes, using django 0.96 with built in cache backend. Apache2 with
mod_python. I believe I installed the memcached python bindings as
well as they explain on the django tutorial.

Here is my -vv output, and it doesn't seem like connections are being
closed. Once in a while there will be a dump of about 100 connections
being closed all at once.
