Last time this was discussed there was some reason given NOT to merge 
this tesrunners modifications into Zope itself. I did not understand 
those reasons. Could somebody that understands them reiterate them and 
we can try again?

I still don't see why we can't use one testrunner to run all tests, 
including CMF tests. It would be nice it ZopeTestCase was included with 
Zope default too, since it really makes it much easier to write unit 
tests in Zope.
