this is precisely the point i was making. either you agree that unprivileged users can get easy access to a scheduling class that can reliably DOS the system, or they can't. if they can't, what kind of scheduling class can they access easily?
according to andrew, and i agree with his conclusion, many people agree that its OK for them to get access to the DOS class, but there's little agreement on the security model to allow this. Con is suggesting that they are not, but instead get a different scheduling class that is functionally equivalent except that it can't (theoretically) be used to DOS the system.
