      My guess is that the CPU architecture is not to blame. The filesystem type must be.

          QTRY_COMPARE(model->rowCount(root), oldCount + count);

      On my Linux system, oldCount = 5 (the number of files created by prepareTestModelRoot and count is the input from the QFETCH.

      The CI is also reporting that the test would have succeeded if the wait was for 11 seconds, which means the filesystem notification did happen at some point. Why that was delayed, I have no clue.
