>
> In Replication Throttling, the leader is more stable, particularly at low
> throttle throughputs, than the follower, as the leader uses Purgatory's
> Delayed Fetch feature to terminate a blocked request early should the quota
> no longer be breached.
> We can simulate the same behaviour simply on the follower, by altering the
> way the back-off works in the AbstractFetcherThread so that, for replication
> throttling, it checks the quota, during the pause, to see if a new request
> should be sent early.
