-Allow the output of a job to be listed. This is pretty easy since we
-know the tmpdir and the output file.
-
For Whentools.once and Whentools.max:
- Add a ~group parameter so we can run no more than "n" jobs in one
- Add a ~kill_oldest (bool) parameter so we can kill the oldest jobs
and start the new job.
-
-Implement native dynlink.
