I suspect that by now you are the only direct consumers of 2.6.18-xen. Is
there really any benefit to keeping the public tree now? Only you commit to
it; I expect only you directly inherit from it (others might indirectly, I
accept). I really don't think we should be tempting anyone else to actually
*use* it as is. Hence my conclusion we could just delete the damn thing.
