Python Notebook checkpoints + a second connection to a given notebook from the same user should disconnect the first one.
Idea: Fabric notebooks should support checkpointing and autosave checkpoints. Also, there should be a maximum of one connection with cell editing permission to a notebook from a given user at a time...
(We also just had an instance of the notebook contents just disappearing ... which, like Patrick, occurred when more than one user had the notebook open for collaboration.)
