Stackless does not monkey-patch socket, gevent and eventlet do, but
I'm not about that. We can just have another socket implementation
that cooperates and use it in cooperative code.

I'm about how to start coroutines and switch between them — the way
it's done in greenlet (but not the implementation) is more preferable
to explicit cocalls.
