What you said is right. But that's not the full story. 

If we look at Adi's code more carefully, myList is not a
List<Gtk.Widget> it is a List. vala doesn't manage a List's member. 

The remaining ref adi observed, I bet, is the ref held by myWidget.
Gtk.Widget.destroy sends a destroy signal to all ref holders of mywidget
asking them to release the reference. The signal was ignored. This
reference is released when the variable myWidget leaves its domain.
