> In testing I saw an AssertionError come up several times when I was trying to
> do failover between two NNs where one or the other was in safe-mode. Need to
> write some unit tests to try to trigger this -- hunch is it has something to
> do with the treatment of "safe block count" while tailing edits in safemode.
