I don't understand step 4.

I get the creeps about whether the system is runtime suspended
or runtime resumed when we come to resume proper, so I need
Kevin to have a look at this.

Apart from that it looks good.

Stephen and Tony are trying to figure out the details of whether "active"
is necessary or not in a related thread I think.
