Emacs has been unexec'ing for as long as I can remember (which is longer than
I can remember Python :).  I know that it's been problematic and there have
been many efforts over the years to replace it, but I think it's been a fairly
successful technique in practice, at least on platforms that support it.
That's another problem with the approach of course; it's not universally
possible to implement.
