our system in an idle state, the CPU spikes every couple of minutes, but at no
defined interval. This does not happen on 2.1. I've been observing the system
using sar and top. So far as I've read, I believe the threading model was
completely rewritten for 3.0, so I'm not sure if that is playing a role...
