Yeah, that's _a_ design, but doesn't really address the
question.  The program author still has to make some kind
of design decision about what to do if the file exists
when the program starts up (suppose someone starts it
directly, without running the script that deletes the files
ahead of time?).

More generally, the issue in this discussion is that the
request for a feature has been wrapped up in details about
the implementation of that feature.  From my observation,
that's the central source of friction.
