Yes, this isn't the first attempt to kill xenstored from this script.
It might be worth having a really-stop-i-know-what-im-doing target

Watches aren't preserved, so for example netback's watch
on /local/domain/0/backends/ gets lost and you can't start any network
backends even after you start xenstored again, similarly for other
device types.
Same thing for any domU's you might have running, they will loose the
ability to attach and detach devices, the watch on the control node
which controls reboot etc goes away etc.
