: It cannot be done without appropriate operating system support, and
: few systems provide such support.  In particular, 99% of Unices don't.
: You are out of luck, I am afraid.

Just a wild idea I've got now -- assuming you have the same binary on both
systems (identical architecture/os), you dump core (SIGQUIT), take the core
to the other machine and let it continue.  For purely computational proccesses
(i.e. those which doesn't talk to various special devices, etc) this might
even work...
