> A user aggressively used the compactrange command.  This queued dozens of Repos in zookeeper.  Pulling new Repos from zookeeper is fairly slow.  Checking if they are ready, is also slow.  The threads running the Repos would not finish getting through the list of Repos, some of which had finished, before the first item in the list was ready to be checked again.
