When (at least sometimes) exceptions occur during shutdown, warnings
like the following appear:
Exception TypeError: "'NoneType' object is not callable" in  ignored

This is apparently meant to be read as 
Exception <<TypeError: "'NoneType' object is not callable" in ...>>
[was] ignored

instead of, for instance
Exception TypeError: "'NoneType' object is not callable" in ignored

Even when parsed correctly, it is a bit mysterious (who/what ignored the
exception?) to one not in the know and has generated more than one
python-list thread.

Suggestion (from John Machin): reword to something like

Shutdown ignored this exception: TypeError: "'NoneType' object is not
callable"

This would tell people that they might need to find out more about the
shutdown process.

Would it be permissible to change this in 3.1?
