+Really might be the issue: Threads with many messages duplicate more\r
+often than messages with few messages. Threads with only one message\r
+never seem to come up more than twice.\r
+Currently I don't have the time to track down what actually get's stored\r
+in match_set, would be nice if a dev could shed some light on it. Thx!\r
