output_filter.sh:
        Comment added to address HDFFV-8270.  The sample ontput in the
        file's comments are not up-to-date with the scripts in the file
        that remove output unique to certain systems when running test
        scripts.  This output doesn't match expected output files for
        the tests, causing them to fail.  Ther output_filter.sh file
        removes such output.  Currently we don't have access to these
        systems to update the comments.

testflushrefresh.sh.in:
        flushrefresh and other SWMR tests have been failing
        occasionally but regularly since bringing them to the develop
        branch.  The logs and debugging point to unexpected deletion of
        signal files as the point of failure, and John Mainzer suggests
        that two such tests running simultaneously in the same directory
        may lead to the operating system deleting the other test's
        signal file. Running the flushrefresh test in its own directory
        seems to solve the problem.
