+    expr: a callable accepting a port number, specifically one of the items
+    from portlist. If calling that callable raises socket.error with
+    EADDRINUSE, freeport() retrieves the next item from portlist and retries.
+
+    Returns: (expr(port), port)
+
+    port: the value from portlist for which expr(port) succeeded
+
+    Raises:
+
+    Any exception raised by expr(port) other than EADDRINUSE.
+
+    socket.error if, for every item from portlist, expr(port) raises
+    socket.error. The exception you see is the one from the last item in
+    portlist.
+
+    StopIteration if portlist is completely empty.
+
+    Example:
+
+    server, port = freeport(xrange(8000, 8010),
+                            lambda port: HTTPServer(("localhost", port),
+                                                    MyRequestHandler))
+    # pass 'port' to client code
+    # call server.serve_forever()
+    """
+    # If portlist is completely empty, let StopIteration propagate: that's an
+    # error because we can't return meaningful values. We have no 'port',
+    # therefore no 'expr(port)'.
+    portiter = iter(portlist)
+    port = portiter.next()
+
+    while True:
+        try:

+            # Here we want the next port from portiter. But on StopIteration,
+            # we want to raise the original exception rather than

+            type, value, tb = sys.exc_info()
+            try:
