Btw, I'd like to state it again - the patch I sent out was not ready to be 
applied. I'm pretty sure it should check things like certain vm_flags 
too(VM_LOCKED etc), and fall back for those cases as well.

So the patch was more meant to illustrate the _concept_ than meant to 
necessarily be taken seriously as-is.
