[plug] Is there a way to put a job to sleep so it can survive a reboot?

[Bill Kenworthy]

I have installed chpox (freshmeat) which does a checkpoint of the
desired process(es).  I now have a 194Mb file of the checkpoint.  The
docs say there is a way to do the cwd and open files at the same time,
but the detailed docs are in Russian(!) so I haven't figured this out
yet.   I have ~200Mb postscript file (so far) representing some 13
graphics (plots) of the data that appears to be being written to in
bursts so there is a bit of work yet to confirm that it will do the job.
