    Well, such things happen all the day in a "in-development" system and therefore people/developers are happy having some laboratory rats testing. But is this worth a whole message on a news platform?

      Benchmarking for regressions is important to the one guy who runs this site (and is interesting to at least some of its readers).

        It's neat to compare kernel schedulers to what we have in nature. The CFS is a good, yet simple, demonstration of how reciprocity works. I wonder what the result would be if we decentralized the scheduler and made each thread schedule itself. Would an empathetic scheduler, where threads can cooperate together, work any better? Perhaps I should look at Frans De Waal's research and make a tech demo.
