Thanks - quite a bit better to understand.

The one thing I'm still missing for both changes is a brief word on
why qemu-xen-traditional doesn't want/need this and - as iirc
you said - if that one manages to get this implemented without a
similar race, why upstream qemu can't do things in a similar way.

Also iirc someone responded to v1 with a comment saying a race
like this is an OS bug - I don#t think I've seen a response to this.
