Yes. But now you seem to imply that running wl_display_roundtrip() in parallel
to a threaded mainloop is not meant to work. Well, the Wayland developers are
free to "define" their API the way they feel like, so that is fine.

But then I don't understand what you meant by "it all works if all threads
follow the polling protocol documented". That seems contradictory.
