Well, that is one of the most interesting use cases, indeed! :-)
Seriously, I really expect to have some very hard time when I'll come to
consider scenarios like that one...

Glad to know my patches are (well, could be!) useful for something!
About cpupool, I think if a domain is created as part of the pool, the
very same behaviour you achieve with my patches should be expected.
However, as George is correctly pointing out, that might turn out to be
quite bad if the domain is then moved! :-(

Dario
