	With the current assumptions that change notifications make, it is not
	possible to connect p to q and q to p.

	The reason is that the notification will only be delivered some time
	in the future (due to the requirement that they are asynchronous, i.e.
	do not cause the sender to block) - but this means that two different
	change notifications (i.e. changed to 1.0, changed to 2.0) may move
	in a cycle between the two objects p and q, if p and q are cross
	connected. So don't cross connect ;).
