This was implemented for 1.0 out of paranoia about the possibility of needing to schedule reboots of the system after it went out in the field, which I am happy to say was never ever used. Let's get rid of it. A small stub is left, to still service the API that allows people to send a reboot broadcast to have the system immediately reboot.
