As I said previously, tzickel, this is an edge case in Python 2.7 which means it has a low priority for most core developers. Realize that we are also working towards a Python 3.5.1 release and a 3.4.4 release as well (which will be the first and last bugfix release for those feature releases, respectively). Compare that to Python 2.7 which probably has 10 more bugfix releases and where this issue has now existed for five years and this is the first report for it, meaning we are not rushing to get it done with other pressing issues to work on.

I realize it's serious to *you*, but that unfortunately doesn't translate it to it being as important to everyone else so please be patient. If this is still an issue for you then consider deleting all of your .pyc files and switching off bytecode file generation: https://docs.python.org/2/library/sys.html#sys.dont_write_bytecode .
