So I implemented absolute_url in my python base class with the call to
aq_parent.absolute_url done with relative=1 instead of just passing
relative.  Why does OFS.Application.Application call aq_acquire if it
doesn't inherit from Acquisiton.Explicit? 

This solves this problem, but I get another one.

In CatalogAwareness, in the url function, there is a call to
self.REQUEST['SCRIPT_NAME'] - but I get an error saying REQUEST doesn't
exist.  How the hell does Zope decide when you have access to self.REQUEST
and when you don't?  I can't seem to find any way to tell when it'll work or
not.
