> The reruns are a mess. JD and I looked at it a bit but aren't sure what's
> going on. One possibility is that we're not giving the cluster enough time to
> start back up on rerun. Or maybe the threads launched by ITClient stick
> around across reruns (they aren't explicitly made into daemon threads).
