            // Stream the index from disk but only check if the stream is valid.
            using (var fileStream = new FileStream("Temp/Read.index", FileMode.Open, FileAccess.Read, FileShare.Read))

                Debug.Assert(copyIndex.Read(fileStream, checkVersionOnly: true));
            }

            // Completely stream the index from disk.
