            <title>[SERVER-9471] hold write lock between finishing a batch and updating the oplog</title>
                <link>https://jira.mongodb.org/browse/SERVER-9471</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Right now we drop the write lock between finishing a batch and updating the oplog (and notifying upstream that we&apos;ve applied ops).&lt;br/&gt;
This allows queued readers to run, and will delay our reporting of our progress upstream.  This may in turn needlessly delay write concern getLastError calls on the primary.&lt;/p&gt;</description>
