I'm not sure I understand what you mean by old state and the GUI - all
that's really necessary here is to determine what Galaxy considers to be
the state of the job (new, queued, running), recreate the in-memory job
components (the JobWrapper), and place the job back in Galaxy's
DRM-monitoring queue, which will then proceed with the process of
finishing the job if it's finished in the DRM or waiting for it to
finish if it's still queued or running in the DRM.
