Sounds good, thanks. Don't get me wrong -- I am not really opposing your
solution (because it's of course quite close to what kgraft is doing :p ),
but I'd like to make sure we understand each other well.

I still have to think a little bit more about how to handle kthreads
properly even in your proposed solution (i.e. how exactly is it superior
to what kgraft is currently doing in this respect). We'd have to go
through all them anyway, and make them parkable, right?
