Message 253863 - Python tracker

TL:DR
Python 2 forgot to do I/O error checking when reading .py files from disk. On some rare situations this can bite Python in the ass and cause it to bork .pyc files.

Checked python 3, it checks the I/O in a different / better way.

Next python 2.7 is out in 1.5 month, I really want this fix to get in, did I forgot to nose some developer who can help out ?
