[Newcomer] Some unit tests fail on Python 2.7.3

[choksi81]

'''Problem'''
A good portion of Repy unit tests pass on Python 2.7.2 but fail on 2.7.3, due to the same error:

Exception safety_exceptions.RunBuiltinException: RunBuiltinException() in <bound
 method Popen.__del__ of <subprocess.Popen object at 0x030D7CF0>> ignored

I tried running this on Python 2.7.3 on both Linux and Windows 8. No such exception was encountered. Below is a run-down of the steps for execution:
