While working on creating this image, I noticed that Bert was right. There
is a #becomeForward: happening inside the block that's passed into
#allObjectsDo:. It's because #allObjectsDo: is called from
#obsoleteBehaviors, which sends #isBehavior to all the objects. If the
image happens to contain an instance of MCInfoProxy, the DNU causes it to
download the full ancestry and become it.

However, I don't see why that would cause the sentinel object not to be
enumerated.
