I know you wouldn't look at Plone for an example :p so here's an example
from Silva:
https://infrae.com/svn/Silva/branch/zope-2.10/tests/layer.py

Look at SilvaZCMLLayer, which does the setup for all of Silva's
integration tests.  It has ``zcml.load_site()`` and it also registers a
subscriber for anything (for which you can use your own list just as well).
