Indeed, that would be the right fix. Since Wayland is fully
asynchronous, create_prime_buffer will either succeed, or generate a
protocol error much further down the line.

That being said, the use of wl_display_roundtrip is really broken in
the presence of multiple threads: much like Jonas's fix for
wayland-egl, all the Wayland objects created by the WSI _must_ use a
separate event queue.

Cheers,
Daniel
