Python's bool type is a subclass of int, so the function that handles
system exit converts False to 0. In terms of process exit codes, 0
means success. On Windows the exit code is set in "errorlevel":

    >>> raise SystemExit(False)

    C:\>echo %errorlevel%
    0

    >>> raise SystemExit(True)

    C:\>if errorlevel 1 echo spam
    spam
