Hello, I heard Chris say in one of the lectures/workshops that one of the ways you could advance time was to increment the clock by 1usec at a time and check what's happening at that point. However, this would mean for things like longsleep, there would be 5 million operations of checking the state of just one process, which is very slow. And if there were 10 longsleeps, then every process would need to be checked 5 million times each, which would be even slower. Have I misunderstood what he meant by incrementing 1usec at a time? Or is incrementing by 1usec just *one* of the ways you can do it, but perhaps not the best? Thanks
