To use this function, `ein:console-security-dir' and

This function works best with the new python.el_ which is shipped
with Emacs 24.2 or later. If you don't have it, this function
opens a \"plain\" command line interpreter (comint) buffer where
you cannot use fancy stuff such as TAB completion.
It should be possible to support python-mode.el. Patches are welcome!
