I have not tested ZFS, that might be a good one. If you are running this
on Xen 3.4 the behaviour should be the same as without this patches, so
there shouldn't be many differences.

If you could try that on Xen 4.0 at least (if I remember correctly
that's when the vector callback was introduced), you should see the PV
timer getting attached, and a performance increase.
