Just a note. The data I referenced in my other post that can be found
on comp.arch uses 64k pages as the smallest page size in the study.
Pages sized 1M and 16M were the other two.

As I understand it, only a few arch's have hw support for more than 2
page sizes, but my response is that they will eventually need them.
The larger the memory, the larger the possible page size needs to be
too. Otherwise you are just pushing out the problem for a few years.
