Major Description
It's currently a bit awkward to safely get the full list of log segments, because you first have to take a log anchor on the MinimumOpId(), then get the list of segments, and then re-anchor on the minimum OpId returned in the segments map. It would be more user friendly to just automatically pass a LogAnchor* to Log::GetReadableLogSegments() and have it anchor for you, but this requires a little plumbing so leaving as a TODO.
