         where the return value from process_connect() is the return value of the
         call it makes to process_connect_service().
     
    -    It is safe to make a refactor by moving the call of do_take_over()
    -    into the function process_connect().
    +    Move the call of do_take_over() inside process_connect(), so that
    +    calling the process_connect() function is more concise and will not
    +    miss do_take_over().
