Hi Dave,
I'm not sure how relevant page table sharing has to the halloween deadline since it's not a feature per se, just an optimization. It has more to do with getting numa ia32 boxes to survive, so it's an ideal out-of-tree patch.
Anyway, I feel your pain - debugging these deep VM hacks can get very weird. I just got back home, I'll have a read through your latest.
