	I havn't looked at the code; but this sounds just horribly evil, and
"not the done thing" - it is normal to use GObject data for this sort of
thing, instead of something like this - that is unless you need to
override virtual methods or something; even so I'd be inclined to
inherit with the same size instance/class and use the GObject data.

	Really.
