      Description

      The world was rosier before October 19-25, Karam Singh says.

      The 100K 1 second sleep job used to take around 800mins or 13-14 mins. It now runs till 45 mins and still manages to complete only about 45K tasks.

      One/more of the flurry of commits for 0.23.0 deserve(s) the blame.
