   @marcoabreu Please see the latest commit which addresses your concerns.
   
   Adding this here as we discussed this offline, but it may come in helpful if someone else has to work on this:
   "Jupyter client throws RuntimeErrors and TimeoutErrors if there are issues with the execution harness. Unfortunately Jupyter client throws away further information so the only further detail we have is the error message itself. See https://github.com/jupyter/jupyter_client/blob/master/jupyter_client/blocking/client.py (RuntimeError/TimeoutError).
   Fortunately we're surrounding just one line with the try/except block that catches Runtime and Timeout errors."
   The decision above is that RuntimeErrors and TimeoutErrors are too general, so we will only retry on the specific RuntimeError we've seen during integration runs.
