They call the kernel sleep() routine with lbolt as a parameter, and the system issues a wakeup call with the address of this variable every second (every 60 clock ticks on a 60HZ machine). I'd be surprised to see a process in a "zombie" state if it were waiting on a reliably deterministic event like lbolt.
