Hmm. Is that really a good idea? I think pretty much everyone
is agreed that this patch shouldn't be applied to mainline in
its current form (that is, without any insight into why the patch
has such an effect on performance). And I'd got the impression the
purpose of the branch was to hold patches that are fit for mainline.
(Hey, has anyone ever had to argue so hard _against_ getting
one of their patches applied? ;))
