That is what Emacs does, and it causes them a lot of trouble. They're trying to move away from it at the moment, but the direction is not yet clear. The keyword is "unexec", and it wrecks havoc with malloc.
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. -Barry
