Good idea!  That helped a lot.  I deleted
src/zope/interface/_zope_interface_coptimizations.so, allowing me to use
pdb to discover it was trying to instantiate a
'zope.traversing.namespace.view' with only one argument.  That looks
like a Zope testing bug to me, but I need to concentrate on solving
other problems, so I changed my code to directly instantiate the view I
needed.  Now the tests pass again.

For me, the value is in the comfort of a transparent database.  I want
to know exactly what Zope is storing.  FileStorage makes that fairly hard.
