[Zope] More about the TinyTable problem

[Ricardo Newbery]

Just now noticed something else wrong related to this TinyTable 
trouble I'm having.

When I log out and hit the site as unauthorized, I now get the following error:

   Error Type: UnpickleableError
   Error Value: Cannot pickle <extension class 
Acquisition.ImplicitAcquirerWrapper at 2836f9a0> objects
