+        <p>
+        If a dataset's storage layout is 'compact', care must be taken when
+        writing data to the dataset in parallel.  A compact dataset's raw data
+        is cached in memory and may be flushed to the file from any of the
+        parallel processes, so parallel applications should always attempt to
+        write identical data to the dataset from all processes.
