> Starting all regionservers at the same time will mean that most 
> PeriodicMemstoreFlusher's will be running at the same time. So all of these 
> threads will queue flushes at about the same time.
> This was supposed to be mitigated by Delayed. However that isn't nearly 
> enough. This results in the immediate filling up and then draining of the 
> flush queues every hour.
