Re: Exception Propagation

No, he means something like...

  task body T is
    ...
  begin
    ...            -- Do one time task "setup" code here.
    loop
        ...        -- Do task "setup" code needed to "restart" here.
        begin
            ...    -- Main body of task.
        exception
        when others =>
            ...    -- Do "exception recovery & reporting" code here.
        end;
    end loop;

  end T;

This task can not be terminated by any exception, it just "restarts" at the
loop.

The "exception recovery & reporting" code might be null.
