Sorry, I've had to refocus my energy on other non-virtualization
tmem-related issues* for awhile so haven't had a chance to work
on the future balloon driver features you are proposing.

What is the difference between 2.6.36 balloon driver and Jeremy's
xen/balloon tree head?  I think ideally the kernel version for
development should be the latest (2.6.36).
