+ * This code has a bug:
+ *
+ * It is possible for a connect result message from another
+ * connect attempt to be processed here first, because we
+ * start listening to the multicast group before starting
+ * our own connect request, which may succeed but we get a
+ * fail message from a previous attempt that raced with us,
+ * or similar.
+ *
+ * The only proper way to fix this would be to listen to events
+ * before sending the command, and for the kernel to send the
+ * connect request or a cookie along with the event, so that you
+ * can match up whether the connect _you_ requested was finished
+ * or aborted.
+ *
+ * Alas, the kernel doesn't do that (yet).
