Keep persistent write-ahead log for long-lived ops like split, merge, and data syncs via pub/sub that would allow cleanup after restart of crash. Some ops would be kept, like split/merge, and possibly used to speed DVID-to-DVID push/pull. Others would only persist until the op is completed. This would also handle issue #98.
