Comment(by neena):

 The assertion is failing because it is executed before the
 _confchanged_listener can finish updating the cached value. One way to
 make the test pass would be to have it sleep for a few 100 milliseconds
 before running

 {{{
       self.assertEqual(['mno,tuv,wxyz'], controller.get_conf("nodefamily",
 multiple = True))
 }}}

 The right way to do this would probably be to, umm, lock a lock when
 CONF_CHANGED occurs and wait for it to be released in the get_conf call.
