>
> In the case that a replica is consistently behind the other replicas, we may
> be able to detect that the node is slow and evict it. (Currently under high
> write load we very often degrade to all tablets having just two live replicas
> and one COPYING)
> * In fact, this would also be useful for leaders that are significantly
> slower than their followers.
> * We should instead recruit a new replica and only evict the lagging one once
> the new one is online.
