• removes the hacky method that adds temporary jobs to queues in order to get an accurate queue length; it now isn't as accurate but it doesn't break everything, so that's probably better
• increases the tolerance for queue lengths; i.e. it will only reach "amber" alert when there are 2 queued items (not including currently processing) and "bad" when there are 4
