Instead of creating one thread per domU, wouldn't it make much more
sense to use another mechanism, e.g. a workqueue, to deliver the
watch events? This would be one central place, wouldn't need any
changes in Xen tools or complex mechanisms to select the correct
thread, save resources, and domUs would benefit, too.
