Nitpick, but I actually think it's important: gtk_widget_destroy will
allways "destroy" right away.  The refcounting stuff might delay the
"finalization" of a widget but not its destruction.

"Destroy" in the context of Gtk means: destroy the XWindow, remove the
widget from its parent and destroy all child widgets.  "Finalize"
means basically: free the memory of the widget struct and all other
system resources like the memory for a char* label.

This is done so that you can "destroy" a widget reliably at any time
you want but keep the struct around until no pointers to it exist.
