Solve the following python programming problem given the following code:
def _install_signal_handlers(self) : 
    'Installs signal handlers for handling SIGINT and SIGTERM
        gracefully.
        ' 
    def request_force_stop(signum, frame) : 
        'Terminates the application (cold shutdown).
            ' 
        self.log.warning ('Cold shut down.') 
        if self.horse_pid : 
            msg = ('Taking down horse %d with me.' % self.horse_pid) 
            self.log.warning (msg) 
            try : 
                os.kill (self.horse_pid, signal.SIGKILL) 
except OSError as e : 
                if (e.errno != errno.ESRCH) : 
                    self.log.debug ('Horse already down.') 
                    raise 
raise SystemExit () 
def request_stop(signum, frame) : 
        'Stops the current worker loop but waits for child processes to
            end gracefully (warm shutdown).
            ' 
        self.log.debug (('Got signal %s.' % signal_name (signum))) 
        signal.signal (signal.SIGINT, request_force_stop) 
        signal.signal (signal.SIGTERM, request_force_stop) 
        msg = 'Warm shut down requested.' 
        self.log.warning (msg) 
        if (self.state == 'busy') : 
            self._stopped = True 
            self.log.debug ('Stopping after current horse is finished. Press Ctrl+C again for a cold shutdown.') 
else : 
            raise StopRequested () 
signal.signal (signal.SIGINT, request_stop) 
    signal.signal (signal.SIGTERM, request_force_stop)
