I've always heard that what makes checkpoint/restart hard is having
to handle asynchronous events.

The Berkeley NOW project was going to do checkpoint/restart as one
of their initial projects but it never happened. If I remember
correctly, it turned out to be harder than they thought to do
completely right.

Cordially,
