--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
The fun here is that the race is expected. All that we need to annotate is that
the read/write is atomic (without actually setting a barrier). So long as the
actual use of the slot is atomic, there can not be two threads that succeed in
accessing the same slot simultaneously.
