Hi Quentin,

I'm still trying to make sense of the results, and I believe that has
to do with not using perf to get the timings, as the noise increases
considerably. Unfortunately, my kernel is a bit on the old side and
manually compiled a long time ago. I wouldn't hold your commit because
of that, as it was within expected ranges anyway.

If I can spot anything bad later, I'll fill a new bug and we can look
at it. Shrink wrapping is an optimisation I wanted, so let's just get
that that in. :)

cheers,
