I have no longer a 2.4 tree to figure out how, but I think it's not too hard to do. As for side effects, you might probably note that the machine will spend more time scheduling tasks. Not only because it has to schedule 10 times more often, but also because 2.4 doesn't have the O(1) scheduler 2.6 has. Erik -- They're all fools. Don't worry.
