And suddenly we have a little more auditability.  Who rebooted the DB  
at 3pm?  Dave did!

It also would allow for some more logic to be applied, in the case  
someone screws up a script and sends 200 reboot requests in a short  
period.  The first is acknowledged, perhaps the other 199 are marked  
INVALID because the machine is already REBOOTING.
