I was able to reproduce this on an HP-UX machine. What happens is
that /sbin/reboot (which is run by /sbin/shutdown) sends a SIGTERM
signal to all processes before it calls the reboot system call.
When sudo receives the SIGTERM, it passes the signal to the command
it is running (shutdown or reboot) which kills the reboot process
before it has had a chance to actually reboot the machine.
I don't have a good solution for this at the moment.
