Thank you for the pointer! This is nice.

Out of curiosity, for objects that are only released when a client
disconnects (such as wl_registry), how does the Wayland server know how to
release this if the client does not disconnect explicitly. in other words
how is the resource leak on the server side avoided if the client just
exits and the OS cleans up?

Thanks again,
