Yes it's correct if you don't expect it to free the window. From any
language, a GtkWindow will live until someone explicitely calls its
destroy() method. GtkWindow widgets don't disappear just because the
last reference to them was droppped.

The self ref/sink for GtkWindow occurs inside it's init() method,
you can't intercept it, and it would be broken if you could.
