IPython ThreadedShell failing

[Former user]

On Python 3.7 with IPython 7.0.1 all is well. But on Python 3.8 with IPython 7.10.1 (at least on Windows), we have a problem:

python -m Shady world --console=python

works, but if you use the default shell, --console=ipython:

python -m Shady world

then the shell (and hence the World) quits as soon as it starts.
