Hello,  
I’ve been looking at `ray.util.multiprocessing.Pool` and python’s implementation of `multiprocessing.Pool`. Here’s what I found in python’s implementation that may not be in Ray core yet? I might be wrong.

I can only see `Pool.map` in ray but I’m more interested towards `Pool.starmap_async`. Is there a way that I can achieve this with Ray?

Thanks in advance!
