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 ;).
