<pre>When launching Weston on a raw X server (i.e. no window/display manager),
Weston blocks indefinitely in x11_output_wait_for_map and never maps onto the X
display:

It appears Weston never receives a XCB_CONFIGURE_NOTIFY event on a raw X
server. It runs fine under a gnome X session.
Steps:
1. X -noreset :666 & sleep 1 && DISPLAY=:666 weston
