AIUI all gtk calls have to happen on the default main context and so on
the.  Even if this is a different thread, the issues around locking the
default main context make the glib mainloop go mad.

There's a lot of history, too much of it, so it obscures. I think the
bug I filed is at https://gitlab.gnome.org/GNOME/gtk/-/issues/2315

[In your case I think the _exit() there only to prevent the glib main
loop from spamming errors when it gets into an inconsistent state, the
issues are in glib, but I've not refreshed my unreliable memory]
