> Is there a use case for sharing an event loop across forking?

I don't know if asyncio must have a builtin support for this use case. The minimum is to document the behaviour, or maybe even suggest a recipe to support it.

For example, an event loop of asyncio is not thread-safe and we don't want to support this use case. But I wrote a short documentation with code snippets to show how to workaround this issue:
https://docs.python.org/dev/library/asyncio-dev.html#concurrency-and-multithreading

We need a similar section to explain how to use asyncio with the os.fork() function and the multiprocesing module.
