+ * response arrives that proves no such event is coming, or an I/O error
+ * occurs.
+ *
+ * After processing a request, the X server sends responses in a specific
+ * order. First come any events that the request generated, then any
+ * replies for the request, then the error response if there is one. After
+ * that, the server may spontaneously send more events with the same
+ * sequence number, which are not related to that request.
+ *
+ * This function will always return events from the pre-reply phase of the
+ * specified request. It may also return events from the unrelated
+ * post-reply stream, as long as they have the same sequence number.
+ *
+ * This function is useful for callers that need to process responses in
+ * wire-order.
+ *
+ * Implementation note: You cannot currently use this function to ensure
+ * that you process responses in exactly wire-order, because depending on
+ * the sequence of calls you make and the timing of server responses,
+ * post-reply events with the same sequence number may be returned as part
+ * of the pre-reply event stream, even though they were separated by a
+ * reply or error. In practice this kind of error is unlikely to matter,
