Run the handlers for replication commands as background processes. This should improve the visibility in our metrics, and reduce the number of "running db transaction from sentinel context" warnings. Ideally it means converting the things that fire off deferreds into the night into things that actually return a Deferred when they are done. I've made a bit of a stab at this, but it will probably be leaky.
