That is how I implemented it in pulsar. I'm not sure it is the best way,
but it works.
It could also be a method in the EventLoopPolicy. Something like


class EventLoopPolicy(asyncio.AbstractEventLoopPolicy):

    def task_factory(self):
        return ...

    def new_event_loop(self):
        return EventLoop(task_factory=self.task_factory)

its own. I'm not sure how greenio task interoperate with asyncio event loop.
Pusar uses greenlets without the need of a greenlet-specialised task class.
