I'm very new to Condor but this doesn't strike me as the kind of
functionality that belongs in the job management system.
You've said your job writes to stdout -- if that's the case, wouldn't it
be trivial to just add "|bzip2 >outfile.bz2"? No intermediate storage,
no NFS thrashing, no added code in an already complicated job control
system... And I don't think this would even be platform-specific, as
even Windows (IIRC) supports i/o redirection.
What am I missing?
