Gilles demonstrates a situation where

        rename x,x/lock  fails (observing user is not file's creator)
but     rename x,y       succeeds

Even so, shouldn't the results be the same for both attempts
(both or neither successful)?

Or are the rules still different because POSIX has no concept
of lockwords?
