This sounds interesting. I wrote such a routine some time ago
for a CDC Cyber, and it was *very* useful.
I was thinking about writing something like it for unix,
but the problem seems to be the stack. I couldn't figure
a way to initialize the stack from a core image.

Anyone has any ideas how to perform that feat?

If *this* is my opinion, I wasn't sober at the time.
