Comment (by Dhalgren):

 Just noticed the handy Unbound statistic "requestlist max X avg Y".

 Going back I see typically the maximum pending DNS query list runs around
 600 with an average length of around 300.  Max has been steady but average
 tripled over 12 months to the present value.  Occasional extreme case is
 3000 for a day, sometimes two.
