this is not random.... it is deterministic. typical round-robin times are on the order of 10ms, so you would have a significant amount of non-context-switched

this is not random.... it is deterministic. typical round-robin times are on the order of 10ms, so you would have a significant amount of non-context-switched 'random' numbers, which when combined with analysis using the cycle counter.... namely a counter running at the clock-speed of your processor would yield a very non-random value.
