(was: I suppose it wouldn't matter much in our case then, since we'll be using `topology.disruptor.batch.size = 1` (etc). I say do the PR, just cos why not...)

> We've been running Storm's snapshots on our production cluster for a little while now (that back pressure support really helped us), and we've noticed a sudden spike in system load when going from commit@ba1250993d10ffc523c9f5464371fbeb406d216f to the current latest commit@c12e28c829fcfabc0a3a775fb9714968b7e3e349. Both versions were running the exact same topologies, and there was no significant change in workload. Not exactly sure how to even begin to debug this, so we ended up just rolling back. Thoughts?
