It might not be necessary to have a pseudofilesystem for terminals.
Since the terminal need only be 'owned' while it is in an open state,
it should be possible to temporarily override the ownership that
VOP_ACCESS, stat, and friends report by adding a user structural
reference / hook to the device structure which the VOP code can tap
off of.
