NetBSD man page says:

     IPC_RMID   Remove the shared memory segment specified by shmid and
                destroy the data associated with it.  Only the super-user or a
                process with an effective uid equal to the shm_perm.cuid or
                shm_perm.uid values in the data structure associated with the
                segment can do this.

which matches

but my latest run did not leave one lying around.  So maybe this was
just one odd test that got fixed.
