def myexit(code):
    '''
    Substitute for sys.exit.  MUST be used at EOF.

    This wrapper flushes output and calls `os._exit`.

    Python 2.7.10 on NetBSD 6.1 x86-32 has a bug that causes the
    interpreter to hang after the program has finished if it has ever
    called `subprocess.Popen`.  All of `exit`, `sys.exit`, `quit` and
    end of file are affected.

    Using `os._exit` won't work either because output is buffered and
    not flushed on exit.
