File Locking And Block Execution

    import scalax.file.{FileOps, Path}

    val file: FileOps =  Path ("file")

    // By default the entire file is locked with exclusive access
    val result: Option[String] = file.withLock() { s =>
      s.slurpString

    // if the filesystem does not support locking then None will be returned
    result match {
      case None => file.slurpString // oh well this is the best I can do
      case Some(data) => data
    }

    def fail: Nothing = throw new AssertionError("Uh oh")

    // or perhaps we only lock part of the file
    val result2: Traversable[Byte] = file.withLock(10, 20) { s =>
      s.bytes slice (10,20)
    } getOrElse {fail}
