What you are describing here sounds more like the process
checkpointing functionality that Softway (I think it was) developed
sometime last century.  There should be a paper on it in an AUUG
Conference Proceedings somewhere.  Process checkpointing is somewhat
different to suspend/resume: With suspend/resume, you are saving the
entire system state - which is basically a matter of dumping physical
RAM to disk and being able to restore it later.  You don't need to be
able to isolate individual processes and there's no need to 'reopen'
file handles because they will automatically re-instantiate when you
restore the kernel state that included them being open.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
