My original goal was to evolve towards a state where this could go
away when userland deleted all the routes to the interfaces and
addresses on the interface and brought the interface down.

i think that having the kernel delete all this state automatically
when the device goes away feels like the "wrong answer".

Getting the system to not crash when a pcmcia card containing a device
which is connected to an interface was ejected was the first step.
Considering that I know of a few people running L*n*x on laptops
specifically because we crash when we do this, it seemed like this
would be a reasonable short term goal ..

But I guess I'm just too much of a pragmatist.. :-)
