> The new {{SegmentWriteOperation#internalWriteStream}} method checks whether
> the input stream to write is a {{SegmentStream}}. If it's, writer will reuse
> existing block ids, rather than storing the whole stream.
> It should also check whether the blocks in {{SegmentStream}} comes from the
> same tracker / segment store. Otherwise this will create invalid references
> if someone invokes the {{internalWriteStream()}} method with a
> {{SegmentStream}} created externally.
