-----------------------------------

@Nicolas, this is only for 89-fb. Trunk has already splited the dead server's log in parallel in another way.

> When one region server goes down, the master will shutdown the region server and split its log.
> However, splitting log is a blocking call and it would take some time.
> If more than one region server go down, the master will split its log one by one, which is not efficient.
> Since we have the distributed log split, we could split these logs from the dead servers in parallel.
