apache线程的apr\u pool\u destroy（）安全吗？

我的应用程序是用apache构建的，在windows上运行。我正在使用createThread（）创建一个线程，然后为每个线程执行以下操作：

ap_run_sub_req( subrequest );   
ap_rflush( subrequest );  
ap_destroy_sub_req( subrequest );  

ap_destroy_sub_请求依次调用apr_pool_destroy（）函数

ap_run_sub_req（）为池分配内存，ap_destroy_sub_req（）释放分配的内存

如果在线程内调用apr_pool_destroy（），则分配的内存不会被释放，从而导致我的应用程序内存泄漏。我在任何apache文档中都没有提到apr\u pool\u destroy（）是非线程安全函数

这个问题怎么解决？？如何释放线程内分配的池？

从外观上看，它不是线程安全的，但我不是C专家。您可能应该在上发布。
