    then we'll first have wait for those X changes to at least be done in a
    minimal manner so that they can be tested for real with RSDL. (is it
    _really_ due to that? Or will X regress forever once we switch to RSDL?)
    We cannot regress the scheduling of a workload as important as "X mixed
    with CPU-intense tasks". And "in theory this should be fixed if X is
    fixed" does not cut it. X is pretty much _the_ most important thing to
    optimize the interactive behavior of a Linux scheduler for. Also,
    paradoxically, it is precisely the improvement of _X_ workloads that
    RSDL argues with.

    this regression has to be fixed before RSDL can be merged, simply
    because it is a pretty negative effect that goes beyond any of the
    visible positive improvements that RSDL brings over the current
    scheduler. If it is better to fix X, then X has to be fixed _first_, at
    least in form of a prototype patch that can be _tested_, and then the
    result has to be validated against RSDL.
