        * gobject.c: placed a comment about not changing CArray until we have
        g_object_list_watched_closures().

        * gparam.h (struct _GParamSpecClass): added padding.

        * gobjectnotifyqueue.c (struct _GObjectNotifyQueue): abuse
        g_list_alloc() to allocate GObjectNotifyQueue to et rid
        of locking issues.
