Very interesting that this hasn't come up before (or has it?).  It has
always amazed me that this is not a standard feature of all operating
systems, and I have had to implement various kludges over the years to
enable checkpoint/restart capabilities.

Please respond practically to the above request, but I would also like
to see a philosophical discussion on the subject either here, with reference
to UNIX, or elsewhere, in more general terms.
