vnd is peculiar in that it spawns a unit whenever it is opened and
removes it again when it is closed.
VNDIOCSET for the same unit marks it VNF_INITED on success, and then
VNDIOCSET for a different unit spawns that unit first and then marks
It would be simpler if there were a static dedicated control unit that
is used only for creating / purging other units.
