Hmm.. I'll have to draw up a new hit list of suspicious changesets. The
difficulty of bisecting a problem when we have two separate repositories
uinvolved (xen-unsatble and the qemu repo) is something we may have to
consider after 3.4 is out. It's worked okay so far but it does rather break
down when the bugs hit the fan!
