And the timescale for shipping new features is getting longer. The 
slaves have been working in the IPv6 coding mines for several years 
now. Any changes we need due to multi6 need to be modular increments,
rather than fundamental change in the stacks, if you want to see them
shipped on a reasonable timescale.
