   For some reason, I have a vague memory of reading somewhere that   
   it was considered "more robust" to check for a negative return   
   value, and not just -1 specifically.  Perhaps this was just   
   superstition, or perhaps someone had been bit by an overly   
   permissive environment.  It certainly seems like advice that we   
   can safely discard at this point.
