What happens currently? Can 'xm reboot' wait forever because it races the
re-creation of the domain?

We need a better test than domid. It's not guaranteed that a domain will get
a new domid when it restarts. Perhaps xend should support the wait option
(since it is involved in the restart), or we could add a restart sequence
count to xenstore (but xm oughtn't to access xenstore directly).
