The
unique_temp_dir()helper in pet-pipenv tests usedSystemTime::now().as_nanos()to generate temp directory names. On Windows,SystemTimehas ~15.6ms resolution, so parallel test threads can get the same value — causing one test's cleanup (remove_dir_all) to destroy another test's files mid-execution.Fix: Replace the nanos-based name with
process_id + AtomicU64 counter, which is guaranteed unique across parallel test threads within the same test binary.This was observed as a flaky
