      Description

      The durable history branch has a failing Python test case, which is part of the long running test suite. The failure is:

      [2020/02/13 10:56:00.766] FAIL: test_cursor13.test_cursor13_sweep.test_cursor_sweep (subunit.RemotedTestCase)

      [2020/02/13 10:56:00.766]     raise self.failureException(msg)
      [2020/02/13 10:56:00.766] AssertionError: 2 != 499854
      

      We need to understand why cursor sweep isn't behaving as expected, and try to figure out how to pull this test into the short test suite (so we can see the failure sooner)
