I'm not sure if I would have included JOB_STATUS_CREATED, i.e. before
the job has even started, but it's not necessarily a problem. The
implementation just need to be careful to work even in early stages. But
probably the early stages include some part of JOB_STATUS_RUNNING, too,
so they'd have to do this anyway.
