While I remember there is another concern that doesn't seem to be
addressed in this patch series. What happens when a guest is paused?
I think exclusive locks should be converted to shared locks in that
case, since (only while the guest is paused) it _is_ safe to fish
around inside the guest's state. Of course the lock must be restored
before the guest resumes.
