Well. The third solution is making the next releases of Zope 2.10 and 
Zope 2.11 required for GenericSetup 1.5.

Importing directly from App.class_init exposed a circular import issue 
in Zope, see: 
http://mail.zope.org/pipermail/zope-cmf/2008-December/028003.html

I fixed that issue on Zope 2.10 and Zope 2.11 trunk and added 
InitializeClass as alias for default__class_init__.

If you really need to run GenericSetup on older versions I'd prefer your 
first solution (BBB import from Globals) because it makes sure modules 
are imported in the right order.
