Comments are as always welcome!

Care to explain what this is useful for? (Not saying it's a stupid  
idea,
just wondering what the reason for doing it is).

In my case, I use it to test parts of my memory controller patches  
on an
emulated NUMA machine. I plan to use it to test out page migration
across nodes.

Can you explain that further.  I'm still not clear on why this is  
useful.
