It's not just this bot. I also found failures on [aarch64](https://lab.llvm.org/buildbot/#/builders/59/builds/2999) and [arm](https://lab.llvm.org/buildbot/#/builders/18/builds/2079).  I don't see it on the mac bots, but I don't know how to look further into the history for those. The only way I can reproduce the problem is the same way that you can -- run the test many many times and try to catch it happening. For a relatively rare failure like this you may need to run it hundreds of times (and also put some background load on the system to make scheduling more nondeterministic) to catch it. I'm pretty sure CentOS is not immune to this bug.
