title: Does pygtk garbage-collect runtime-created functions connected to signals?
body: <p>I'm using PyGtk.</p>
  
  <p>Will a <strong>runtime-generated</strong> function connected to the signal "drag_data_get" of a widget be <strong>garbage-collected</strong> when the widget is <strong>destroyed</strong> ?</p>
  
  <p>Same question about the Gtk.TargetList that are created and associated with drag source/dest target?</p>
  
  <p>I did found <a href="https://stackoverflow.com/questions/6866578/python-and-gtk-how-to-create-garbage-collector-friendly-objects?rq=1">Python and GTK+: How to create garbage collector friendly objects?</a> but it does not help too much.</p>
