Sorry about the confusion. I think my original point was simply one
of surprise that sys.argv wouldn't essentially mirror the elements
of the command line which I used to get there.
The specifics of my use-case weren't really too important.

For completeness, I'm talking about the cherrypy Autoreloader which
attempts to restart (via execv) whatever process was responsible for
loading it in the first place, via an identical or equivalent command
line. The current (cherrypy) code simply joins sys.executable and
sys.argv but this fails in the face of python -m as we have seen.

The cherrypy package has no especial knowledge of the structure of the
application which imported it and so must piece together the command
line somehow. Clearly, I can take various approaches of the sort
which you've outlined, or subclass the reloader, or fetch the original
command line from the OS, etc. It's not that this is a showstopper,
merely slightly surprising. (To me).
