As an additional note, I think that we should probably wait for a keypress, or wait either 10 seconds or a keypress, (or exit and ask to be relaunched with a command line option, eg: `--exploit-me`). I know it's annoying, but there is a remote code execution vulnerability here; if you simply print a warning and get on downloading the file and running its setup.py, it might be too late for the user.
