<p>The current context seems to be a permanent backlog of ~40 items in the Close Review Queue. In answer to the original question "What can be done":</p>

<ol>
<li><p>Suggestion: we could recruit 10 more reviewers to each review 20 a day and then taper off as the queue gets manageable.<br>
Problem: how to find them?</p></li>
<li><p>Suggestion: we could find out why Kjetil has 50 votes on another stack and see if we can get the same here.<br>
Problem: he and others who currently review might not want to do 50 a day and concentrating so much in the hands of a few reviewers is not best practice as their idiosyncrasies dominate the site.</p></li>
<li><p>Suggestion: moderators could have occasional purges when things get beyond non-mod users' capabilities.<br>
Problem: community moderating is preferred, see 2 above.</p></li>
<li><p>Suggestion: reduce our efforts to clean up the site by only issuing votes-to-close three or four times a day which if we then review 20 keeps it in balance (I think).<br>
Problem: this defeats the aim of having a site of good quality questions and answers.</p></li>
</ol>

<p>I agree this all comes from the Department of the Blindingly Obvious but perhaps others may have contributions.</p>
