wayland-egl.c is blocking

[rtbo]

Blocking in wl_display_dispatch, which should be replaced by wl_display_dispatch_pending as long as surface is not configured.
This is what weston/clients/simple-egl.c is doing.
Also what I am doing here in the D bindings: https://github.com/rtbo/wayland-d/blob/master/examples/egl_window/source/egl_window.d

You mean calling wl_display_dispatch as long as the surface is not configured? Because that is what the weston example does. Your example does it the other way round.

No, I'm doing it the same way, but my flag is reversed! (wait_for_configure == !configured)
AFAICT, calling wl_display_dispatch will block if the window is not configured. (I'm not pretending to understand why)
