testris always times out under python3 on windows

[tangentstorm]

On windows, running under git bash:

/c/Python33/python testris.py /c/Python33/python learntris.py just times out, even though /c/Python33/python learntris.py runs correctly.

The given learntris.py implementation is:

import sys
sys.stdin.readline()

(Which should pass the first test.) The --shell option makes no difference.

All variations work fine under python 2.7.6:

/c/Python27/python2 testris.py --shell /c/Python33/python learntris.py
/c/Python27/python2 testris.py --shell /c/Python27/python2 learntris.py
/c/Python27/python2 testris.py  /c/Python33/python.exe learntris.py
/c/Python27/python2 testris.py  /c/Python27/python2.exe learntris.py

Interestingly, the following learntris.py implementation does not lead to a timeout:

pass

Since the timeout occured when sys.readline() was invoked, this may indicate an issue with the way python 3 is sending line endings.
