Cool. I see that this affects Spyder as well. IPython in bare terminal doesn't run that code but produces a neat traceback (no internals, just user code) by default. |

Yeah, it'll be a very neat improvement in both the notebook and Spyder. |

The original code no longer worked as intended because modern Python versions require
from Noneto suppress the previous context, and as a result a long traceback of ipykernel internals was being printed when pressing the Stop button.This PR fixes the suppression and adds a debug message to make it easier to it easier to understand what happened.
