Try:
sys.stdin.buffer.fileno()
or maybe
sys.stdin.buffer.raw.fileno()
In Python 3.x, sys.stdin isn't actually a "file", it's a TextIOWrapper
around a BufferedReader around a file (io.FileIO).
TextIOWrapper is responsible for converting a stream of bytes to a stream
of (Unicode) characters. BufferedReader is responsible for buffering (like
C stdio).
