test bug

  def test_open_io_opens_filepath_and_passes_file_to_block
    # not a great test....
    s = IoSample.new
    
    was_in_block = false
    s.send(:open_io, 2) do |io|
      assert_equal $stdout.stat.dev, io.stat.dev
      assert $stdout.object_id != io.object_id
      was_in_block = true
    end

    assert was_in_block
  end

First the integer should be 1, not 2 (this doesn't cause an error on mac, for some reason). Second this is a bad test.
