Yes. True. No argument there. Unfortunately, the state of IPv6
implementatino deployment __today__ is such that if we want to ship
code that works at sites with IPv4, plus "early" IPv6 services,
we also have to ship with IPv6 turned *off*.

I guess that means we need either two kernels, or two userlands: one
with IPv6 on, and one with it off.  Also, dont forget the small-footprint
devices which plausibly cannot afford the bloat of IPv6.

*Sigh*.  Just as much of the world is waking up to the problems
with IPv6, we're ramming it down everyone's throat?
