There's one problem that I know of. There cannot be any outstanding 
request in the backend, but all repsonses have to be collected. I have 
tried to use a time in the frontend's .suspend function, but that did not 
work. The reason I believe is the __cli() call in the reboot.c before 
xenbus_suspend() which prevents functions like wait_event(), 
interruptible_sleep_on_timeout() and related ones to work properly. Can 
this function be moved to a  later point?
