为什么异步内核测试在编译的Python 3.6中失败？

我已经编译了Python 3.6并运行了测试，但有两个测试失败：

======================================================================
FAIL: test_handle_expt (test.test_asyncore.TestAPI_UseIPv4Poll)

哪里会出错？

这在bug追踪器上出现了两次：

第一个已作为第二个的副本关闭，第二个尚未修复。简言之，显然是这样。你需要等他们修好它。在此之前，可以安全地忽略这些故障

你用的是Mac，对吧？是的，我刚看到罚单上写着一个答案：-。顺便说一句，在扫描相关问题后，通过在bugs.python.org上创建一个问题，您有更好的机会解决您的问题。这里-在4分钟内：-D
