So at least it's not some sort of daemon process, then. Does it need a
GUI (hope not)? If it has limited input/output requirements, you might
be in luck with some of the tools that don't require recompilation. I've
even heard of checkpoint migration for "vi" as something that has been
done (though there's probably some trick to it), so presumably it would
be possible to save/restore compuational apps. Esp, perhaps, if it only
needs stdin and stdout. Not sure.

I think someone mentioned user-mode Linux. Would that make be possible?
