    I'd say they will listen if you are able to make a convincing case that
    this is a real problem. The problem with scheduler patch and the threading
    benchmark is that it optimizes performance under completely impossible
    conditions, breaking real world performance. The (in)famous Mindcraft
    benchmarks were also shot down, but the real problems uncovered were
    considered carefully.
