More digging. The client hangs because the X server ignores the request in this
code:

    /*
     * Ensures an out of control client can't exhaust our swap queue, and
     * also orders swaps.
     */
    if (DRI2ThrottleClient(client, pDrawable)) 
        return client->noClientException;

(from ProcDRI2SwapBuffers())
