title: memory leak in Zend_Db_Table_Row?
body: <p>This is the code I have:</p>
  
  <pre><code>&lt;?php
  $start = memory_get_usage();
  $table = new Zend_Db_Table('user');
  for ($i = 0; $i &lt; 5; $i++) {
    $row = $table-&gt;createRow();
    $row-&gt;name = 'Test ' . $i;
    $row-&gt;save();
    unset($row);
    echo (memory_get_usage() - $start) . "\n";
  }
  </code></pre>
  
  <p>This is what I see:</p>
  
  <pre><code>90664
  93384
  96056
  98728
  101400
  </code></pre>
  
  <p>Isn't it a memory leak? When I have 500 objects to insert into DB in one script I'm getting memory overflow. Can anyone help?</p>
