Public bug reported:
On an IPv6 network, routes have a marked lifetime.
So, if you are connected to two IPv6 networks you may have multiple
default routes.
Not such a problem.

[ what is odd is that eth0 has no link route on it, but whatever this
bug is not about that ]
Note the expiration times on each route, and let's do this again:

That route (on dev eth0) has 'expired' but the time seems to have gone
to infinity. It stays there for a while - after a few minutes (the time
it took the collect this information, submit to lauchpad and me login)
the route disappears.
But it seems to be taking a longer time that you would expect. Well,
certainly I would expect.
