I recall that mysteriously appearing at some stage.  I don't think it is 
a feature since `Switching to process 0' doesn't make any sense - if the 
program exited normally then there are no processes.

I suspect that it is related to the SIM trying to simultaneously be an 
embedded board (which can't exit) and a normal UNIX process (which does 
exit).

I'd KFAIL it for now.  I'm expecting to work on SIM's shortly so will 
actually look at it.
