Review comment:
I don't think there is a need for that. I extracted this private
constructor to make the two public ones shorter. I thought about to pass in
SegmentDirectory, but the pattern of using SegmentDirectory.Writer is to
accumulate as many writes as possible before closing for efficiency. It's
costly to open/close Writer repetitively.
