This option send SIGKILL to daemon after kill_wait period. When daemon hangs and doesn't respond to SIGTERM/SIGHUP there is no way to stop it using swift-init now. Classic init scripts in Linux kills hanged process after grace period and this patch add same behaviour. This is most usefull when using "restart" on hanged daemon.
