FYI. The change I made for memory leak described in: https://issues.apache.org/jira/browse/MODPYTHON-181
has caused a problem with other changes I made for: https://issues.apache.org/jira/browse/MODPYTHON-155 This is causing test suite to hang on the tests: test_req_handler test_accesshandler_add_handler_to_empty_hl The specific problem is caused by code which uses req.add_handler(). If you are using 3.3 from trunk, as long as you aren't using that method you should be okay. I'll try and work out an alternate way of doing what I needed. :-( Graham
