Virtual Memory II: the return of objrmap

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...
