_UnixDefaultEventLoopPolicy doesn't detect fork and tries to re-use the inherited child watcher. [1] is my idea how to fix this.

Andrew, AFAIK subprocesses was something that you worked on at some point. Do you have time to look into this?  Need tests and I'm not sure if I got [1] quite right.

This probably won't make it to 3.7.0, but 3.7.1 seems like a good target.
