Description

I'm experimenting with implementing an asyncio-compatible event loop on top of libuv with Cython. It would be great if there is a way to provide a custom Future implementation. I was thinking about adding loop.create_future() (instead of Future(loop=loop)) API method, as well as an ABC, so that functions like ensure_future would recognize custom Futures. @gvanrossum @Haypo what do you think about this?
