[google-appengine] High Replication - Large CPU spikes without Datastore Access

I've already posted this on the Java GAE group, but maybe someone has seen this issue on a Python-hosted app. I'm carrying out some testing of my app against the HR-store, instead of the M/S datastore, and I've noticed that occasionally I'll get a request which has a massive CPU spike. These spik
