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

[Bill Kenworthy]

This is a numerical job on an ~450000x450000x450000 matrix, and the
software doesn't support checkpointing.  Most of the stuff requires you
to loink in special libs during compile, but there a couple I'll give a
go at over the next few days.

USB thunbdrives are only good for about a million write cycles according
to a spec I was looking at last week, would get a bit expensive to
replace them every few days if you want to write to them a lot.  wouldnt
help my problem anyhow - its the data in memory I need to store.

vmware is one possibility (just sleep the vm between reboots), but there
will be some overhead.  What I was hoping for is some shell that could
do this natively without any overhead.
