It's good to understand the problem some more, and I think I like your 
general approach. However, although your current patch drops the domain 
refcnts, it leaves the tainted-refcnt pages allocated. Worse, they are 
left allocated and with a dangling domain pointer. Probably we should 
hit those page refcnts on the head (i.e., to zero). One fly in the 
ointment is if some refcnts are non-zero because other domains have 
mappings of them (e.g., device model in domain0)...
