      <p>
        Applications must now pass the DB_NOSYNC flag to the methods
        - <code class="literal">DB-&gt;remove</code>,
        <code class="literal">DB-&gt;rename</code>,
        <code class="literal">DB_ENV-&gt;dbremove</code>, and
        <code class="literal">DB_ENV-&gt;dbrename</code>, to avoid a
        multi-database file to be flushed from cache. This flag is
        applicable if you have created the database handle in a
        non-transactional environment.
    </p>
      <p>
        By default, all non-transactional database remove/rename
        operations cause data to be synced to disk. This can now be
        overridden using the DB_NOSYNC flag so that files can be
        accessed outside the environment after the database handles
        are closed.
