patch 8.0.0955: Test_existent_file() fails on some file systems

    patch 8.0.0955: Test_existent_file() fails on some file systems

    Problem:    Test_existent_file() fails on some file systems.
    Solution:   Run the test again with a sleep when the test fails without a
                sleep. (James McCoy, closes #1984)
