I wasn't (unfortunately) able to control that variance :(
Reading the results again, I tend to agree though that the difference
might be noise. I also think that the change per se doesn't introduce
any benefit so i'm less inclined to keep going for this route. I don't
exclude this might have some utility though, that's why I attached the
patch to the mail, in case somebody wants to play with it a bit more.
