I looked at trying to apply the same logic to the Xen side of things but

FWIW, there's a bug in this original implementation. See Konrad's "misc"
tree - for the fix:
http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=commit;h=f6c958ff0d00ffbf1cdc8fcf2f2a82f06fbbb5f4
Here is the original thread where I submitted the fix:
