* although the new proxy may not be useful until a queue is attached.
* The following code is safe to perform in the context of the test, since
* we are not flushing the display write buffer, neither explicitly
* (wl_display_flush()) nor implicitly (we don't place enough data to
* fill the display buffer and cause an auto-flush). */
