    For the purposes of this discussion again, let's say "fixing nice"
    means say "group schedule each nice level above 0". There are
    obviously many possibilities here, but let's consider this one

    How, exactly, under what scenario in a "multi-user machine" does this
    break? How exactly is it orthogonal?

    Two people logged in would get their "make" jobs group scheduled
    together. What is the problem?

    Since Linus appears to be more interested in talking about nipples
    than explaining exactly what it would break, but you appear to agree
    with him, hopefully you'll be able to explain...
