This uses a 32bit hole in the GObject structure on 64bit arches as a flag field which can be optionally used for some preformance hints. Currently there is a flag that gets set any time you connect to a signal on a GObject which is used as early bailout for signal emissions, and using the flags field instead of a user-data for checking if a GObject is under construction.
