  67 This tests that objects from plugin objects are properly cleaned up.
  68
  69 Example:
  70    plugin
  71      ------- (Creates) ------ Object1
  72                                   ------- (Creates) ------ Object2
  73
  74 It is important that both Object1 and Object2 cleanup as a result of
  75 cleaning up the plugin.
