It seems module invocations used in a discussion page has no way of refreshing. For example, Module_talk:TNT/testcases contains unit test results of a module. There seems to be no simple way to purge that page... In the longer term, might need to rethink where unit tests can be stored - talk pages seem to no longer be a good place for them, but storing them in the Module namespace is not possible (unless somehow show it as a part of docs?)
