Given that Ingo's reworkings led to horrendous interactive performance for many desktop users for a long time during 2.5, it seems a little odd to prefer crediting Ingo over Con given what you've said. How about just mentioning that we have an O(1) scheduler, plus there has been significant work on interactive performance. john -- Khendon's Law: If the same point is made twice by the same person, the thread is over.
