That is a surprising statement given what we just discussed. Things 
are not lean and fast but weirdly screwed up. The policy layer is 
significantly impacted by historical contingencies rather than designed in 
a clean way. It cannot even deliver the functionality it was designed to 
deliver (see BIND).

Individual physical page migration is quite different from
address space migration.

Address space migration? That is something new in this discussion. So 
could you explain what you mean by that? I have looked at page migration 
in a variety of contexts and could not see much difference.
