Thinking about this some more it might be preferable to
write /local/domain/domid/console/{backend,backend-id} giving us a
concrete pointer to the backend we wish to destroy, this would cope
better with console backends in dom!=0 too.
I'm assuming its not a mistake that the backend exists in the first
place?
Ian.
