People keep asserting that, but I don't think we have enough
experience with the explicit-switching-point-markers-all-the-
way-up style of coding to tell whether it's a good idea or not.
My gut feeling is that the explicit markers will help at the
lowest levels, where you're trying to protect a critical section,
but at the upper levels they will just be noise that causes
In one of Guido's earlier posts (which I can't find now,
unfortunately), he said something that made it sound like
he was coming around to that point of view too, but he
seems to have gone back on that recently.
