The second paragraph sounds as if this is a correctness fix,
i.e. "should not be added" hints that we would see a wrong result
returned from the hashmap if you added these entries to the
name_hash.  If this is a performance-only fix, that should be more
clearly stated.  Also, can we have performance numbers in the
proposed log message as well, or is the improvement too small to
measure?

Thanks.
