The zope.testing package has a way to work around this from setup/ 
teardown functions passed to the DocFileSuite (or whatever wrapper 
you're using). See the module zope.testing.module for the functions.
Essentially, the __name__ needs to be set in test.globs; class 
construction uses the global value for __name__ to provide __module__; 
doctests normally don't have one, so it acquires the value from 
__builtin__.__name__ instead. Which is, of course, horribly wrong.
The solution in zope.testing.module allows the class to be used with 
pickle within the test as well.
