ceilometer collector is working off a single thread. this makes processing data very slow... also, we don't see any QueuePool issues because of we only ever have one connection writing to the db.

seems related to monkey_patch. if we eventlet.monkey_patch(socket=True, select=True, thread=True, time=True), the connections to db jumps to multiple connections but we run into QueuePool issue again.
