When there's already a page fault happening on every memory access, I have some doubts of the
significance of such additional overhead.

Well, hmmmm, I guess I was thinking just enough to stick my foot in my mouth :-)

Also the extra memory accesses will tend to blow the cache more if you use 
more memory to track the uninit state.
