    Description

      This occasional failure occurred:
      https://github.com/apache/arrow/pull/11148/checks?check_run_id=3662252735#step:10:583

      [ RUN      ] AsyncReaderTests.InvalidRowsSkipped
      D:/a/arrow/arrow/cpp/src/arrow/csv/reader_test.cc:205: Failure
      Expected equality of these values:
        NINVALID
          Which is: 50
        num_invalid_rows
          Which is: 49
      [  FAILED  ] AsyncReaderTests.InvalidRowsSkipped (2 ms)
      

      I'm not sure what this is due to, since CSV parsing is supposed to be deterministic? Is this test parsing blocks in parallel?
