I also said that I wanted to fill "gaps". Process number math introduces
another source of typos, and would have to be adjusted each time.

While that adds another opportunity to make things more readable, it also
adds another opportunity to forget the maths in a single place, and 
overwrite the output of another already finished job.

What I was initially looking for was a way to (re-)run job # n from a 
job cluster, perserving its job ID. To what extent does Condor rely on
consecutive job ids within a cluster?
