• • Tim will get to this after the upload.wm traffic

• JobQueue related
  • make a edit rate limit for addressing any potential issue from Max’s exercise (whether or not his was the cause)
  • bump the jobqueue warning threshold? so it is actually listened to
    • social issue: an alarm must be handled :-D (even if end result is to raise threshold)
    • Andrew Otto is looking into this type of thing, Greg will swing back with him
