Own of course.

Is there a way to cancel an outstanding lock request? How? You seem
to think that there's no problem.

Actually I think an cmo_close on a handle that has outstanding
requests of any kind should drop them, so I was incorrect about
killing the session being the only way. Maybe I can create some
kind of ncld_open_locked() by using that feature. That ought to
be good enough.
