I think that's basically the way to do it (and it should work fine on OS X,
too). One caveat, though. Is web2py ready to start as soon as VERSION is
written? If there's any housekeeping (unpacking or the like) that needs to
happen first, the restart might be premature.
Also, might it be useful to have web2py touch a timestamp file when it starts
(well, not if it's under GAE, but otherwise)? That would give us a hook for an
uptime function, as well as supporting this functionality.
As with my caveat, it has a bit of a race problem, since the timestamp file
gets touched some finite time after the restart event. Maybe something like:
if test... ; then
sleep 1
if test...; then
now do your stuff
