> The following are reasons of reusing the pool and AP.
> # A update-heavy application, for example, loader, creates many BufferedMutator for batch updates. But these BufferedMutators can’t share a large threadpool because the shutdown() method will be called when closing any BufferedMutator. This patch adds a flag into BufferedMutatorParams for preventing calling the shutdown() method in BufferedMutatorImpl#close
> # The AsyncProcess has the powerful traffic control, but the control is against the single table currently. Because the AP is constructed at BufferedMutatorImpl's construction. This patch change the BufferedMutatorImpl's construction for reuse the AP so that the updates for different tables can be restricted by the same AP.
> Additionally, there are two changes(aren't included in latest patch) for #2.
> 1) The AP will be exposed to user.
> 2) A new method will be added to Connection for instantiating a AP.
> All suggestions are welcome.
