More misc cleanup

So we've been running for a couple days now
succesfully with this config.  Discovered some
gotchas along the way:

* Things get busy this generates a TON of volumes and accounts on the Cluster
  - Add a cluster cleanup routine when there's nothing in the queue

* Running 8 procs seems unstable, drop it back to 4

* On my current machine I can run 4 simultaneous jobs, bump this up
  when ready to do multi-node
Well, as unpopular as this is WTF
