Those patches look pretty good so you should try to copy their stuff
:)
They ended up never calling detach, I hope you can do that too. Just
always have a blocking or identity domain and just use it everywhere.
Since you can't predict what translation detach gives it should not
be set on a device. release could be the only exception and only if
you reall have to.
