For information: Yann and me have started reviewing/testing/tweaking
this patch series today. We found a number of things to improve, and
I'll continue working on this.
So I'd be nice if Arnout/Peter you could wait before applying this, and
consider it is in my queue of patches to apply. I'll mark the patches
as delegated to me.
Thanks!
Thomas
