> Every DOWNNODE command enqueues N copies of itself into queue-work, where N is number of collections affected by the DOWNNODE.
> This rarely matters in practice, because queue-work gets immediately dumped-- however, if anything throws an exception (such as ZK bad version), we don't clear queue-work.  Then the next time through the loop we run the expensive DOWNNODE command potentially hundreds of times.
