No need for DAGMan to do this... Condor itself will automatically 
restart a Vanilla universe job that fails to complete. By "complete", I 
mean the job executable exits of its own accord.

So if you just need to submit a group of N jobs and have them resilient 
to preemption, crashes, etc, just use condor_submit.  No need for using 
condor_submit_dag.

On the other hand, if you have inter-job dependencies (i.e. after your N 
vanilla jobs complete successfully, you want another job to be 
submitted), then you want condor_submit_dag.
