[issue23548] TypeError in event loop finalizer, new in Python 3.4.3

Just an update to my previous post. We ran into this issue again, but only noticed later because we do not see this problem on Ubuntu Bionic with Python 3.6.5, but we did see it again when we tested later on Ubuntu Xenial with Python 3.5.1.

See: https://github.com/ros2/launch/issues/84

So this seems to be fixed in later versions, unless it's just hidden now within the asyncio debug log messages (though I didn't see anything there either, at a glance).
