There is some preview code available that would decrease the CPU overhead of objrmap, probably to acceptable levels. If that code works as well as it's supposed to work (it's a new data structure, not yet well tested, etc...) there's a reasonable chance the pte based rmap can be replaced.
It's good to see that the last reason that caused me to make the pte based rmap code is finally dissolving. A well working object based rmap is much lighter weight...
