Yikes.  That'd involve moving a lot of control path machinery into the
kernel, particularly for the v6 side where "release" isn't just a
shot-in-the-dark datagram.

Before designing some detailed solution like that, I'd like to see a
project that investigates how this stuff *should* work and looks at
the range of possible solutions.  I don't know whether what you're
suggesting is necessarily part of the answer.  Maybe.
