pdfium, memory leak

[PierreZhangcw]

按照示例运行代码，虽然解析完成了，但是出现了一堆如下的日志信息
(RunnerActor pid=2733035) -> Cannot close object; pdfium library is destroyed. This may cause a memory leak.

您好，感谢您对我们工作的关注！

首先可能要看一下是否正确生成需要的PDF，因为Ray worker在结束后会强制kill Ray进程，可能会导致一些既有库被强制销毁。如果发生错误是在所有PDF都处理完过后，则不用担心。Ray的进程强制销毁也会处理掉这些内容，不会泄露。

如果解析有问题的话，请告诉我们具体是使用了多少pdf，以及详细的配置参数。

不过，我们也怀疑可能是代码中某些pdf对象没有close或者没有写在with xxx作用域内，我们会进行二次检查。也希望您能提供复现所需的配置。

期待您的回复！

@SunnyHaze 好的，这个是在所有pdf处理完成之后的输出信息，那应该没问题，不用管了~
一共处理了9个pdf，最后输出了多个memory leak

方便提供下PDF的长度供我们估计问题么？
以及启动flash-mineru的参数，感谢！
