This test fails because, as far as I can tell, SystemChangeFileTest >>
#testClassRenamed breaks the integrity of an IdentityDictionary.

This IdentityDictionary (call it dict) reports having a key in
#keysAndValuesDo: such that dict at: key raises a KeyNotFound.

Inspecting dict verifies this weirdness, even though you can see the
key in the inspector's right hand pane.

Ideas?

The diff in the manifests between the last version where this test
didn't fail and where it did looks like this:

$ diff /home/frank/Downloads/TrunkImage.313.manifest
/home/frank/Downloads/TrunkImage.314.manifest

Not terribly enlightening...
