   I'm not going to take this directly, but if it passes muster with David,
   I'm happy. The fewer locking primitives we need, the better, and brlocks
   have had enough problems that I wouldn't mind getting rid of them.

I'm fine with it, as long as I get shown how to get the equivalent
atomic sequence using the new primitives. Ie. is there still a way
to go:

        stop_all_incoming_packets();
        do_something();
        resume_all_incoming_packets();

with the new stuff?
