我在控制台应用程序中的BackgroundWorker(高级OmniThreadLibrary组件)中的主线程有问题。主线程(整个应用程序)中的对象在为后台任务调度工作项时立即死亡。主线程不等待OnRequestDone方法调用

procedure TEntityIndexer.StartReindex;
begin
  if LoadTable then
    // in ProcessRecords method I schedule WorkItems for BackgroundWorker
      ProcessRecords;
  // when ProcessRecords method is done, application is at the end and
  // main thread is destoryed, so object in main thread is destroyed
  // and BackgroundWorker in object in main thread is destroyed too
end;

procedure TEntityIndexer.ProcessRecords;
var
  _id: Integer;
  _omniValue: TOmniValue;
begin
  FVTable.First;
  while not FVTable.Eof do
  begin
    _id := FVTable.FieldByName('record_id').AsInteger;
    WriteLogText(cProcesIndexLog, 'ID=' + IntToStr(_id) + '....PROCESS STARTED');

    _omniValue := TOmniValue.CreateNamed(
      [ovIdKey, _id,
      ovXMLKey, FVTable.FieldByName('mx').AsString,
      ovGenKey, FVTable.FieldByName('created_str').AsString
      ]);
    FBackgroundWorker.Schedule(FBackgroundWorker.CreateWorkItem(_omniValue));

    FVTable.Next;
  end;
end;

有什么解决方案可以解决这种情况吗?

OTL依赖于其主线程中的Windows消息队列。你必须传递信息。这种情况在GUI应用程序中自然发生,但在控制台应用程序中不会发生。将消息循环添加到程序中
