    You certainly have a colloquial attitude.  Do you, perhaps, work
only on single-user machines? Just because you can use something without
breaking doesn't mean it's seriously flawed.  If there is *any* set of
instructions that, from the user level, can crash a privelege-based
system, then that system is *broken*. 

    Again, just because it's broken doesn't mean it can't be useful for
limited applications - like single user operation.  But when you try to
stress the system, it's going to fail.
