Ok, forget about the notion of objective time then, and just think about
whether the universe contains an observer moment when the oberver
perceives that the computer has gone through an infinite number of
cycles. The answer is no in the CSO case since at any given moment in the
universe an ordinary computer would have gone through only a finite
number of cycles.
