I think in an earlier version of the TDP that I sent out, NX reclaim was a seperate thread for the two MMUs, sidestepping the balance issue. I think the TDP MMU also had a seperate NX reclaim list. That would also make it easier to do something under the read lock.
Yes that was my suggestion actually, I preferred to keep things simple because most of the time there would be only TDP MMU pages.
