signal_handler: increase alarm timeout to 5s and use raise instead of exit() 

it seems that exit() causes problems when threads couldn't be stopped
properly, which is the reason why we have to call alarm() in the first place.
therefore, send a SIGKILL to our process and make sure we don't leave any
zombie threads running.
