     Its difficult or impossible to save the state of the kernel and restore the
    shadow copy. Its probably easier to save the state of a user program instead
    and restore it should the process dump core. Q to you:- what do you plan to
    do when saved copy of kernel contains information of a process that exited
    after copy was saved but before the kernel panic'ed required to be restored?
