Review comment:
Why is this shared at the Region level. Shouldn't it be at the Store
level (in HStore)?
What does sharing at the region level gain us? Are you attempting to evenly
round-robin store open work over all opening stores in the region? Just sharing
an executor at region level won't do this. If the underlying stores are skewed
the order in which runnables are submitted to the executor will share the skew.
