Indeed, I believe that's safer. It's very unlikely that a user creates a
semaphore named "ace_semaphore_foo" that would be deleted by this
sem_unlink. You're right: someone trying to autoconfigure a fixed
version (i.e. with the sem_unlink after the sem_open) after having tried
a broken version, without rebooting or ipcrm'ing, would still be
affected by the problem.
