C/R demo for Linux Plumbers

[Oren Laadan]

The linux Linux Plumbers will take place in about three weeks.
I'm interested in preparing a nice demo working for the c/r
presentation. Something visible.

For example, start a sort of a "session", checkpoint, reboot,
and then restart the session. The session can be 'screen', or
even 'sshd' (w/o persistent connections).

It's also an opportunity to boost development particularly of
pieces necessary for such a demo :)

Ideas, comment and code are welcome.

Oren.
