The patch is "safe" in the sense that it will only introduce
an inf-loop in those cases where the user used to get an error.
[ Unless of course, the calling context catches those errors.  ]

If we can change python.el to work around the problem, we could install
that workaround in emacs-24 and keep the "remove the inf-loop check" for
the trunk, indeed.
