When the lit unit tests are running, do the tests within the same process run sequentially, or are they in parallel at all? If the latter, there could be some thread-safety issue, although I suspect the tests are run sequentially.

Good question. For each lit test, `llvm-lit` will run it on a separate worker process <https://github.com/llvm/llvm-project/blob/main/llvm/utils/lit/lit/run.py#L74>, so we should be safe here.
