-------------------------------------
I'm going to run a couple of more rounds of tests and then commit the patch without the test case.

> DeleteByQuery, unlike other requests, does not filter out the down replicas. Thus, the update is still forwarded to the down replica and fails, and the leader then sets the replica in LiR. In a cluster where there are lots of deleteByQuery requests, this can flood the /overseer/queue.
