> How do you use SIGCHLD on Windows?

I'm only proposing to use a signal when it's available, on UNIX. So have multiple implementations of the function, depending on the ability to get notified on completion without polling.

On Windows, maybe we could use a dedicated thread to set an event once WaitForSingleObject/WaitForMultipleObjects completes?

The design of my bpo-35479 change is to replace polling with one or multiple events. Maybe we can use an event to wakeup _worker_handler() when something happens, but have different wants to signal this event.

I have to investigate how Process.sentinel can be used here.

I might be interesting to use asyncio internally, but I'm not sure if it's possible ;-)
