title: CI looking for Benchmark class in system/Common.php
body: <p>I have had no issues on my local test machine, but when moving my project to a webhost (I have php 5.3, webhost is on 5.2.17. That is the only difference in the setup) I encounter this error:</p>
  
  <pre><code>Fatal error: Class 'CI_Benchmark' not found in /home/veloxtnt/public_html/system/core/Common.php on line 174
  </code></pre>
  
  <p>I've never run into it before and I can't find what is actually looking for the benchmarking class in <code>common.php</code>... I'm not even using the benchmarking class, and the only occurrence of <code>CI_Benchmark</code> is in <code>system/benchmark.php</code>.</p>
  
  <p>I am quite stumped.</p>
