    • 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
