    I did. Others did it too on occasion.

    My argument was against overusing optimization techniques.
    You cannot speed up kernel by aligning *everything* to 32 bytes,
    or by unrolling all loops, or by aggressive inlining.
    That's too easy to work. You get kernel which is bigger
    *and* slower.
