Actually, #doesNotUnderstand: can do one of three things:
1) do everything by itself;
2) forward the message to another object;
3) create the missing method and retry it.
(3) is relatively rare, but it is the scenario for which I introduced
MessageLookup. It turns out that the new MessageLookup>>#sendTo: is
only good for (3), and the old implementation from the Message class is
appropriate for (2).
I'm applying this patch to differentiate how you restart execution in
the two cases:
