<div>According to the comment in #allObjectsDo: we need the
sentinel because the *execution* of aBlock will allocate
an object - the activation context. So regardless of what
aBlock actually does, we need the sentinel to avoid an
infinite loop.</div>

<div>However, this bug causes the loop to skip over the
sentinel. If the comment is right, we should end up in an
infinite loop. But we don't, we eventually get 0. Why?</div>

It does not skip over the sentinel. It encounters the "end" earlier
because you create a new object after the sentinel was created.<br>
If you do Object new nextObject you get 0. So when the proxy is
materialized and then gets sent nextObject it returns 0<br>
