HTTPServer.shutdown returns but the socket is still open

_x000D_ _x000D_ I have the following code that I use to run a local HTTP server on port 8000: # Omitted imports and irrelevant things for brevity. class ThreadedHTTPServer(SocketServer.ThreadingMixIn, HTTPServer): pass class MyClass(object): server = None def start_server(self): handler = MyPageHandler self.server = ThreadedHTTPServer(('', 8000), handler) server_thread = threading.Thread(target=self.server.serve_forever) server_thread.daemon = False server_thread.start() def stop_server(self): self.server.shutdown() However occasionally when stop_server returns, the listening socket will still be opening. I have verified this by putting os.system("netstat -ln | grep 8000") at the end of stop_server and it often shows that the socket is still listening. Is there a way to only return from stop_server once the socket has been closed?
