    I've done something like this in my page_alloc rewrite (which I'm
    trying to get back into after the Christmas, ah, excesses). Incidentally
    there are several places in the kernel that grab a page just in case
    and then free it if it isn't needed. If that's a zeroed page you can
    put it straight on the zeroed list and avoid a second clear. Maybe
    your patch does this - I haven't looked yet.
