I'd also like to see at least the interface definitions in the h/v tree
if not the implementation right away.

The flip side is that we have agreed that the interfaces are not
considered set in stone / stable until we've had a chance to review the
implementation, so perhaps it is better not to commit them to
xen-unstable.hg right away.

I don't know what the right answer is. Perhaps we should at a minimum
reserve the subop numbers even if we don't yet define what they mean in
the Xen tree.

Ian.
