Test for an empty directory that could be very large if it is not empty?

What is your goal for that? Have you measured the performance difference
and decided *based on objective observation* that it's too expensive?

Certainly ‘os.listdir(foo)’ is the simplest way to determine the entries
in a directory, and thereby to test whether it is empty. That simplicity
is very valuable, and you should have a compelling, *measured* reason to
do something more complicated. What is it?
