Some more incompatibilty:
* ioloop.add_timeout accepts a datetime.timedelta for the timeout
* asyncio.call_later accepts the number of seconds
* handler = asyncio.call_later() stands in pair with handler.cancel()
* Tornado's handler = ioloop.add_timeout() stands in pair with
ioloop.remove_timeout(handler). Even the syntax is different.
It looks like I must write a wrapper or subclasses for different event
loop implementations. I strongly feel that because we have a standard
abstract base class asyncio.BaseEventLoop for event loops,
tornado.IOLoop should be a descendant of it.
