PR30735 reports an issue where llvm-cov hangs with a worker thread waiting on a condition, and the main thread waiting to join() the workers. While this doesn't appear to be a bug in llvm-cov or the ThreadPool implementation, it would be helpful to disable the use of threading in the llvm-cov tests where no test coverage is added.
