Willing to write a patch and give it some preliminary testing? I also
agree with the patch Rik sent in about GFP_HIGHUSER, that's orthogonal
though (even if I suspect it could also have made the problem _appear_
much much more clearly).

I'd like to do a real pre7 one of these days (it's already growing big
enough, thank you), but I'd love to have this issue put at least somewhat
to rest.
