Jon is probably referring to a recurring problem we've noticed with the `libc` tests on HSA that they will sometimes fail when running with multiple threads, see https://lab.llvm.org/staging/#/builders/247/builds/2599/steps/10/logs/stdio. Haven't been able to track down whether or not that's a bug in the implementation or interface somewhere.
