Deadlock Appeared!

procedure TProducer.Execute;

begin

repeat

if n=MAXN then self.Suspend

else begin

n:=n+1;

WriteLn('Produced one item! n=',n);

if n=1 then cons.Resume;

end;

until false;

end;



procedure TConsumer.Execute;

begin

repeat

if n=0 then self.Suspend

else begin

n:=n-1;

WriteLn('Consumed one item! n=',n);

if n=MAXN-1 then prod.Resume;

{ GetItem; ConsumeItem; }

end;

until false;

end;
