address used by device driver routines that need to delay but are not
expecting a device interrupt. 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.
