Since Python 3 uses mostly text, not bytes, LC_COLLATE should not
really impact Python applications. Locales set by setlocale() are not
inherited by child processes.

At least, I understand that setting the locale in Python doesn't
impact the performance of child processes:
--
import locale, subprocess
locale.setlocale(locale.LC_COLLATE, "fr_FR.UTF-8")
subprocess.call("sort long_text.txt > /dev/null", shell=True)
--

But the LC_COLLATE locale can be used by C libraries called from
Python through Python extensions implemented in C.
