RE: Monitor for existing job.

I'd recommend using the APIs. The method here is OK, but can fail when
things go awry, like abnormal shutdowns, etc. Sith the API you can specify
the job name only and see if there is an entry returned for it. If so,
there you are. If not, submit it. Very clean, very easy, works even in CL.
