And this is useful because you don't want processes doing anything while
you try to checkpoint them, right? ;)

right there's always a reason for a patchset :) The freezer is something 
already used by openvz. IBM's Metacluster uses a from kernel SIGSTOP signal. 

I would be in favor of adding a new c/r signal like other operating systems 
have done today and in the past. This is something to discuss.
