saving process

[konjo]

is it possible to save a process and then load it at some point, and it continues to flow.
here's what i mean :

>sleep 10
[1]+  Stopped                 sleep 10
>ps
PID TTY          TIME CMD
5162 pts/3    00:00:00 su
5165 pts/3    00:00:00 bash
5206 pts/3    00:00:00 sleep
5207 pts/3    00:00:00 ps

// for example
>save 5206 outfile
>kill 5206

// then later
>load outfile

and by process i mean all the memory it occupies, so for example if a game doesn't have a save feature you could cheat like this...
i can guess that there's no such a thing, but what do you think:
is this a handy feature?
is it hard to make?

There is cryopid project CryoPID - A Process Freezer for Linux
