Patch looks good, but are you 100% sure that sys.executable is always absolute? (On all OSes, under multiprocessing, etc?)

I can check it better if needed. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue13402> _______________________________________
