    No Jamie, the code leaves a footprint only when it is executed.
    I You exclude the one or two "cmps" ( tipically less than 10 bytes of code,
    adresses included ), the only thing at which We can shoot is at the block of
    code of the cluster scheduler that I leaved into the fast path to better
    optimize longer RQ versus shorter ones.

    Cheers,
    Davide.
