> The container-executor function {{write_exit_code_file_as_nm}} had a number 
> of failure conditions where it just returns -1 without restoring previous 
> state.
> This is not a problem in any of the places where it is currently called, but 
> it could be a problem if future code changes call it before code that depends 
> on the previous state.
