To add a little voice of experience here. I have tried that very experiment.
I was able to get hugs to snapshot itself by imitating how emacs does it.
This much was fairly "straightforward" (in a grungy Unix hackers sort of
sense). However, runhugs was a different beast. I could never get it to
snapshot correctly. I never determined what the problem was, but then, when I
did this, runhugs had a number of problems (it was very new) which may be
resolved by now. I could dig up the code if anyone is interested.
