    bpo-31151 changed ForkingMixIn and bpo-31233 changed ThreadingMixIn to block on server_closer() for processes/threads.

    I propose to add a new opt-in option to get the Python 3.6 behaviour. The old behaviour was wrong, but I expect that some people rely on it.

    I consider that it's a regression, so I pick the release blocker priority. Sorry Ned!

    It would be great if someone(s) could give PR 6911 a review, since it is a release blocker for 3.7.0rc1. Thanks!

    I added the block_on_close class attribute to Python 3.7 and master. I'm not really proud of it, but it's the price of the backward compatibility!
