-// cause access_count_ to diverge from zero and therefore cause the ThreadRef
-// comparison to fail, signaling a race, although it may not be in the exact
-// spot where a race *first* appeared in the code we're trying to protect. There
-// is also a chance that an actual race is missed, however the probability of
-// that has been considered small enough to be an acceptable trade off.
