Are there any performance issues with the seconds approach (scala.io.Source.fromFile(file).getLines()))? If I remember correctly 5 to 10 times slower than SynchronousFileSource, *and* the Source.fromFile used (like in the above) example leaks open FileInputStreams which you never close.
SynchronousFileSource is fast, safe, and uses a dedicated thread-pool for the blocking operations by default – use it instead of hand-rolling file reading.
