That makes me remember a day in my OS and Networking class at college. We were discussing job/process management, and the different methods. FIFO, Round Robbin etc.. We were simulating each technique, taking 5 or so minutes for each. Then we got to round robbin. "Windows NT uses a round robbin job scheduling method" said our professor. Our round robbin simulation then dragged on for the remaining 30 minutes of class.
