It does sound reasonable, but here are a couple of observations:

1) This was proposed before (see the discussion thread starting at
<>).  One
alternative is to avoid renaming the failed scripts altogether, so that
they get re-run on next setup.

2) Even if this change gets applied to CVS HEAD, we still need a new setup
release to make sure this gets used.
