Correction: this PR is useful for `ProcessPoolExecutor` as well. I thought `chunksize` parameter handles infinite generators already, but I was wrong. And, as long as the number of items prefetched is a multiple of `chunksize`, there are no issues with the chunksize optimization either. And a minor correction: when listing the advantages of this PR, I should have said: "In addition, if the pool is not busy when `map` is called, your implementation will also be more responsive, since it will yield the first result earlier."
