There's something I don't understand. When will the thing allocate devices in user mode? Perhaps we can agree that a thing never does any...thing by itself. The only time something is achieved with a thing is when a JOB calls the thing's use routine. Then that thing use routine is executed as if it was part of the job's code. To allocate new devices in user mode a job would have to call the thing in user mode, and we're back to the beginning (at least I think we are).
