restarting xend?

Due to a bug in the combination of Xen and kernel I've been running, I've often had to restart xend with guests running. The process had been :
guest 'hangs' with 100% CPU usage
stop xend
kill xenconsoled
start xend
guest 'comes back to life'

So I'd say it's generally safe - but *don't* stop/restart xenstored !

However, while playing around with Xen4.0, I did find a setting to "shutdown guests when stopping xend" - I haven't experimented yet as to how that affects the situation.
