I think this can easily lead to retain-cycles, as widgets will often 
need a pointer to their window, which must be a weak pointer, as there 
are otherwise no ways to get the reference count of the window down to 
zero, without first having to remove all the widgets who keep a 
reference to their window.

But maybe the widgets explicitly use window_base instead of window?!?
