type
  TMiThread = class(TThread)

    procedure Execute; override;
  end;

  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    FThread: TMiThread;
    procedure OnThreadTerminate(Sender: TObject);

  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{ TMiThread }

procedure TMiThread.Execute;
begin
  repeat
  until Terminated;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  FThread.Terminate;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  FThread := TMiThread.Create(True);
  FThread.FreeOnTerminate := True;
  FThread.OnTerminate := OnThreadTerminate;
  FThread.Resume;
end;

procedure TForm1.OnThreadTerminate(Sender: TObject);
begin
  {Aquí cierro el form, bien podría utilizar Application.Terminate}
  Close;
end;

end.
