[issue11271] concurrent.futures.ProcessPoolExecutor.map() doesn't batch function arguments by chunks

[Dan O'Reilly]

Dan O'Reilly added the comment:

A couple of small updates based on comments from Charles-François Natali:

* Use itertools.chain.from_iterable to "yield from" the result chunks instead of a for loop.

* Add more tests with varying chunksizes.
