> We don't instrument amILeader calls right now. We have a large cluster where
> we find that the overseer isn't processing operations as fast as it should.
> Since all operations are pretty fast even at the 99th percentile, the
> slowdown might be due to amILeader and the ZK update calls.
> Let's start measuring those as well.
