They are probably pages shared with backend drivers (xenstore, blkback, 
netback, etc.). Since domain teardown is asynchronous, those backend 
drivers may still have those pages mapped and be able to update them 
while the save is in progress. It's harmless (but of course false 
positives on the verify test are rather annoying!).
