Comment:
This isn't a bug in MacRuby but a bug in your code. You must always return
unique objects from the data source methods. In your
outlineView:child:ofItem: implementation you are returning new Pair
objects, this will very likely crash the outline view because it does not
retain the objects.

I recommend to cache the Pair objects and always return the same
instances.
