The code looks wrong. If you use holders it could be like this:

Reader:

    loop
       declare
          read and create a local object
       begin
          accept entry call and in the rendezvous
             copy object into holder passed to the entry
       end;
    end loop;

Writer:

    loop
       call to the reader entry passing local holder
       write the object held by the holder
    end loop;

P.S. Using an access type or reference-counted object would reduce copying.
