On second read of this comment:

it says "reduce the frequency of serialization anomalies", which doesn't
necessarily mean that it makes new guarantees, I suppose. I should have
gone to the original source.
Anyway, it's a moot point, because apparently that's just a possible
step along the way toward true serializability, and doesn't need to be
separately distinguished.
