And if we really make this async query come true, I suggest designing resource (i.e. remote connection) management very carefully. When the executor fails in the middle of its execution, it possibly fails to release its own resource; close() in ExecutorEnd() will never be called. As far as I know files and memory are released automatically in the current mechanism, but MED APIs will use their own resources other than them.
