bug#29170: bug29170

[graeme vetterlein]

In case it's of any help tracking this down.

I have never, previously, seen this behaviour in 30+ years or Emacs use.

I am running Buster. I recently switched from cinnamon to Xfce as 
desktop manager, the issue now appears about 10% of the time when I exit 
Emacs (e.g via closing the window using X decoration, or C-x C-c )

Message reads:

Saving clipboard to X clipboard manager...

An that Emacs session NEVER exits:

GNU Emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.5) of 
2021-01-31, modified by Debian

AFYI: the Emacs sessions are 100% (looks to be user) CPU  and Xorg is 
high on the iotop list
