Kernel doesn't connect with Tornado 6.0.0

Just did an upgrade of all my packages and Jupyter stopped connecting to the Python3 kernel. Tornado got upgraded from 5.1.1 to 6.0.0 so uninstalled 6 and re-installed 5, working again.
Also (fyi), saw this error in the console:
zmqhandlers.py:284: RuntimeWarning: coroutine 'WebSocketHandler.get' was never awaited
But I don't think pyzmq==18.0.0 is the cause since it works with that (as well as 17.1.2 previously).

Just saw this in the Jupyter repo: jupyter/jupyter#401
Issue is probably more appropriate there. Closing this one.
