title: Memory is leaking when I create models in a loop in FuelPHP
body: <p>I am running a code like this</p>
  
  <pre><code>foreach ($set as $id)
  {
      $user = Model_Users::find($id);
      $user = NULL;
  }
  </code></pre>
  
  <p>And memory consumption is increased with each loop. Too much to ignore - around 300Kb each time. And number of iterations is hundreds of thousands. </p>
  
  <p>So, there is a question - what I have to destroy or close to keep memory consumption level? </p>
