Add some info, I test the case in my local Ubuntu 16.04 docker container with glibc 2.23, run 1000 times, no hang happen. I think the issue is related with glibc issue showed by huangtianhua, looks it impact glibc [2.26, 2.28), see my local env info in following:

> [----------] Global test environment set-up.
> [----------] 2 tests from Priorities/RWMutexTest
> [ RUN ] Priorities/RWMutexTest.TestDeadlocks/0
> And seems it's ok in debug mode.
> Now only this one test failed sometimes on aarch64, [~aserbin] [~adar] would you please have a look for this? Or give some suggestion to us, thanks very much.
