+ * A #GTcpWrapperConnection can be used to wrap a #GIOStream that is
+ * based on a #GSocket, but which is not actually a
+ * #GSocketConnection. This is used by #GSocketClient so that it can
+ * always return a #GSocketConnection, even when the connection it has
+ * actually created is not directly a #GSocketConnection.
