Thanks.

Do you see the same if you run Emacs as something other a daemon?

We don't make raw Wayland requests anywhere, so it must be a bug in GTK.

Outdated information. The PGTK port of Emacs doesn't do anything close
to that, because GTK doesn't let us.

So why not use exit, which lets the atexit handlers run?

Store the data that is in Emacs core?? How did these people learn to
write software?
