Oops, that was my first intention, then thought it will always
get called (which it does, when churn is called), but w/o
function it's called when loading the extension w/o actually
running it. Right?

Will change that.

Ah, does this work in other architectures? Here, on MacOS, I can
only do:

$ echo $COLUMNS
80

but:

$ env | grep COLUMNS

gives nothing. Similarly:

>>> print os.getenv('COLUMNS')
>>> None

Of course if it gives something on other machines, I'd be happy
to comply ;)
