Because the policy checks the roles on the acquired object?  As Dieter 
points out, 'setDefaultAccess(deny)' should only apply to subobjects 
which do *not* have their own roles.

But that test fails on 2.7.2, as well.  My change was actually to the 
implementation of 'guarded_getattr', which is not tested in 
'testZopeSecurityPolicy' (the location of my original patch);  rather, 
its tests are in 'testZopeGuards' (where my second patch applies).

I have not yet bee able to write a good test there yet (one which either 
passes on the 2.7 head and fails for 2.7.2, or vice versa).
