Sorry.  Sure.  What I was opposing here is Raymond's original claim in this 
thread, which was apparently the reason he wanted to deprecate sys.exitfunc:

"""
The atexit module does attempt to co-exist by introducing code to
register a function in sys.exitfunc if it were defined before "import
atexit" was called.  However, this is unreliable because it depends on
import order and the library is free to introduce an earlier "import
atexit" which would break code relying on the co-existance mechanism.
"""

I claim that there is nothing unreliable or depending on import order here, as
long as all concerned parties do the right thing.  Now if there are other good
reasons to deprecate sys.exitfunc, like it being another way of doing
something for which a better interface is provided, then fine.
