After posting that, I thought to have a look around my own system, to see 
what I could find. I checked one or two GUI apps (e.g. Pan, Konsole) to 
see where their process fd 2 was pointing, and in each case it was going 
to some kind of socket.

What kind of socket? So I thought to check the systemd user journal:

    journalctl --user

and yes, there is a whole bunch of random messages there, including GUI 
toolkit errors, just like old times. ;)
