If I did that then a SimplePythonFile would still be valid if the file was
closed on the python side... seems like the wrong behavior.

python API functions expect you to check for an exception with PyErr_Occured()
and clear it before calling into them again. If you don't things usually work
out OK, except on a debug build in which an assert will trip.
