> Following CASSANDRA-9749 , stricter correctness checks on commitlog replay
> can incorrectly detect "corrupt segments" and stop commitlog replay (and
> potentially stop cassandra, depending on the configured policy). In
> {{CommitlogReplayer#replaySyncSection}} we try to read a 4 byte int
> {{serializedSize}}, and if it's 0 (which will happen due to zeroing when the
> segment was created), we continue on to the next segment. However, it appears
> that if a mutation is sized such that it ends with 1, 2, or 3 bytes remaining
> in the segment, we'll pass the {{isEOF}} on the while loop but fail to read
> the {{serializedSize}} int, and fail.
