If restoring a previously executing program can
recover some *context*, then it makes sense to
restore. If you want to restore a process just to save
bringup time -that is a different issue.

I am working on this with the author of checkpointing
in dragonfly (Kip Macy). Basically, the program author
will decide when to save the context of a process and
it will depend on how it interacts with the system.
Saving a shadow copy of the kernel is rather
difficult.
