checkpoint/restart ABI

[Dave Hansen]

Arnd, Jeremy and Oren,

Thanks for all of the very interesting comments about the ABI.  

Considering that we're still *really* early in getting this concept
merged up into mainline, what do you all think we should do now?

My main goal here is just to get everyone to understand the approach
that we're proposing rather than to really fix the interfaces in stone.
I bet we're going to be changing them a lot before these patches
actually get in.
