宏的嵌套比之前复杂了很多，感觉还是之前linux windows整体分开更清晰些，虽然会多一些外围的循环。

1、windows是怎么测试的
2、这个问题自己是否能复现，并发是怎么测试的

- windows目前没有测试，会记一个todo等windows那边能编译后再测试
- yitao的机器在特定输入下有大概率复现，lingzhu之前的dns core问题目前看也是这个导致的，两个场景可以复现。代码修复后多次运行没有再出现core。

排查下来大概率是由于定时检查ip变没变时调用的非可重入版本gethostbyname，与同步发送时curl使用的gethostbyname函数发生了data race。
