Yeah.  The fault in both cases has an error-code of 3, so a write 
protect fault.  It suggests a pinned page is getting freed into the 
general heap for some reason.  Except there are no complaints from Xen 
about writes into a pagetable, so that makes it look like page is being 
made RO but not (left) pinned.
