@busy is false when the job is paused, which happens all the time because that is how jobs yield (e.g. for mirror at least since commit565ac01f8d). Back when 129 was added (2015), perhaps there was no better way of checking whether the job was still actually running. Now we have the @status field (as of58b295ba52, i.e. 2018), which can give us exactly that information.
