Check the tracker (bugs.python.org) for atexit issues, open and closed. 
I believe there was one about order and whether to make a guarantee. The 
doc might have been changed one place and not another. The newer 
statement is probably correct. In any case, the wrong place should be 
corrected.

Don't know about this.
