This idea would work, but the domU that shrinks may still need
to move some data from its memory into its own swap area.

The problem is measuring how much memory each domU really needs.
I've got some ideas on that, which I'll be presenting at this
year's Ottawa Linux Symposium.  Once I've finished writing my
paper I'll start making some info available...
