I don't understand why internal or automatic jobs should follow a
different state machine. Sure, they won't be in this state for long
because the job is immediately unref'ed. Though if someone holds an
additional reference, it might be visible - I would consider this a bug
fix because otherwise the job stays in READY and continues to accept the
verbs for that state.
