Arguments passed to self.stop are returned from self.wait. It is possible to have multiple wait/stop cycles in the same test. Example: # This test uses coroutine style. class MyTestCase(AsyncTestCase): longer allowed to send a body with 1xx or 204 responses. Exception handling now breaks up reference cycles that could delay garbage collection. RedirectHandler now copies any query arguments from the request keep-alive connection. What’s new in Tornado 3.1 Jun 15, 2013 Multiple modules Many reference cycles have been broken up throughout the package, allowing for more efficient garbage collection on CPython
