    Could you please elaborate, why this is needed and put more info about
    this requirement into this patch description?

    People worked hard to push data allocation from stack to heap to make
    THREAD_ORDER of 0 and 1 possible. So why increase it again and why does this
    help scalability?

    Many thanks and Best Regards

    Ingo Oeser, puzzled a bit :-)
