    Sure, as soon as SystemTap translator supports this new marker mechanism
    we will give it a spin and report results.

    From my view this is a good compromise. We all realized in that long
    discussion thread that we need a way to mark the code in the middle of
    functions that can later be activated dynamically. Mathieu's current
    implementation meets that goal. I will be happy to see this in.
