I think this one would be better.

It avoids reloading from disk; looks like a #changed: is enough to catch
the model update when it happens in a different window.

This is a pretty quick hack.  Everything is set up correctly so if you
!theRepositoryListMorph verifyContents! it catches the update... but it
never gets called.  Ensuring #verifyContents is called would be better,
but I'm too unfamiliar with Squeak to do it by myself.  At least it gets
rid of the error when you select the zombie.
