Putting my notes here so I don't lose them:

• calling run_cell should raise an exception if it fails (but this means we'll have to update a lot of tests)
• community link logic fails when raising an exception with no args (e.g., raise ValueError)
• we shouldn't require ; at the end of each command (sqlparse fails)
• execution in the magic should stop in the first command with errors, and maybe rollback? i think currently it commits each one by default
• I'm getting too many open files error when running test_magic.py
