The manpage of Python2 is clear:
-u Force stdin, stdout and stderr to be totally unbuffered.
stdin is also unbuffered.

It used only used for buffered output. Without the patch,
sys.stdout.name == sys.stdout.buffer.name == '1' :-/
New patch:
- use create_stdio() to create unbuffered sys.stdin
- rename Py_UnbufferedStdoutFlag to Py_UnbufferedStdioFlag
- replace "Py_UnbufferedStdioFlag++;" by "Py_UnbufferedStdioFlag =
1;"
- change create_stdio(): (...)
Note: there is no test for unbuffered input because I don't know how
to test this (even by manual tests) :-p
