   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?
