Ah, it's a temporary file indeed.
But does that mean you can't inspect your logs in real time? All log
files I have ever seen are available under their final name while they
are still being written to.

I see. Yes, then an AtomicFile class makes sense (not for logging
though, IMHO :-)).

And I understand your point about it being available in io or some io
submodule (not a 3-level deep one though :-)). Perhaps you want to ask
on python-dev?
