Review comment:
> Couldn't you just unlock in the call method before returning the
DeleteTable repo?
To be clear, you are suggesting that we move the
CancelCompactions.mutateZooKeeper() from it's current location in
DeleteTable.isReady() to DeleteTable.call()? This seems like a much simpler
change. I think I'm going to hold off from doing anything more until Keith
looks at the FATE ops.
