The whole point about Paul's scheme is that he *is* doing exactly that.
And while does seem odd, I will not dismiss the idea without giving it
a full-length meditation :-)

This should be a rare occurence, so I wonder if it's worth the extra code.
What could be important when the client is a GUI is to limit the number of
updates. Dragging a slider could result in *a lot of* X move events, and it's
probably unwise to try and update the model and all clients for each one.
