Once you have this, you might as well make that granularity
per VMA.

This gives you the advantage of being able to share the
mapping for libc.so ;)

1) Oracle and maybe other large shared memory situations

prohibitively high

2) scientific calculations and other programs with a huge
dataset where TLB misses would be prohibitively slow
