Andrew,

This isn't perhaps mongod primary moving due to mongod restarts from
oo-mongo-setup script by chance is it? I think you mentioned you'd
already addressed that in your deployment based on your comments on
this PR

I haven't had a chance to break out chaos monkey and test a lot of
failover scenarios, I'd like to.
