Let's face it, we're not going to _ever_ checkpoint any kind of general 
case process. Just TCP makes that fundamentally impossible in the general 
case, and there are lots and lots of other cases too (just something as 
totally _trivial_ as all the files in the filesystem that don't get rolled 
back).

What do you mean here? Unlinked files?

Or modified files, or anything else. "External state" is a pretty damn 
wide net. It's not just TCP sequence numbers and another machine.

I think (I think) you're seriously underestimating what's doable with
kernel C/R and what's already done.

I was told (haven't seen it myself) that Oracle installations and
Counter Strike servers were moved between boxes just fine.

They were run in specially prepared environment of course, but still.
