Jobs that have been submitted with a JobLeaseDuration set will survive
a reboot of the submit machine. Anything jobs without the job lease duration
will be checkpointed (if possible) and then resumed or restarted when
the condor_schedd starts running again, but will not be running while
the submit machine is down.
