Calling Zope.startup() seems to cause the tests to die.

Removing the import and call allows the tests to pass.

This code is a complete mystery.  It wasn't failing when I ran the
tests yesterday.  But if I do a checkout -D "yesterday," it fails with
an error on the Zope.startup() call.  It looks like that code should
have always failed.  No idea how it ever worked.
