According to PEP 394, the python command is meant to be Python 2
until at least 2020, so in practice this script will be run with
Python 2 for now (except on Arch Linux); but it seems good to be
more future-proof.
In Python 3, os.write() takes a bytestring (bytes object), not a
text string (str/unicode object). In Python 2 ≥ 2.6, the b'' syntax
is supported and gives a str object, because that was a bytestring
in Python 2; either way, b'1' is an acceptable argument to os.write().
In Python ≥ 3.4, the result of os.pipe() is close-on-exec
(non-inheritable) by default, so undo that where needed.
