Actually, I think we need to keep it.  I just heard from another 
developer who does actually use it for debugging.

I think the real problem is that emergency_restart() should not be 
causing these outputs.  Shouldn't machine_restart() change the 
system_state to SYSTEM_RESTART before it calls smp_send_stop()?
