--- Comment #12 from Michel Dänzer <michel at daenzer.net> ---
It should be fine. You're right that fence_finish can run concurrently in
multiple threads, but even if it returns true in multiple threads, the
fence_reference calls are serialized by the mutex. So the second
fence_reference call will find so->fence == NULL and do nothing.

Have you run into any problems with this patch in your testing?
