Description:
 def kill(self, block=False):
 """ Kill the daemon process. Sends the SIGKILL signal to the daemon process, killing it. You probably want to try :py:meth:`stop` first. If ``block`` is true then the call blocks until the daemon process has exited. ``block`` can either be ``True`` (in which case it blocks indefinitely) or a timeout in seconds. Returns ``True`` if the daemon process has (already) exited and ``False`` otherwise. The PID file is always removed, whether the process has already exited or not. Note that this means that subsequent calls to :py:meth:`is_running` and :py:meth:`get_pid` will behave as if the process has exited. If you need to be sure that the process has already exited, set ``block`` to ``True``. .. versionadded:: 0.5.1 The ``block`` parameter """
