title: Memcache won't flush or clear memory
body: <p>I've been trying to clear my memcache as I'm noticing the storage taking up almost 30% of server memory when using <code>ps -aux</code>. </p>
  
  <p>So I ran the following php code. </p>
  
  <pre>
  $memcache = new Memcache;
      $memcache->connect("localhost",11211);
      $memcache->flush();
      print_r($memcache->getStats());
  </pre>
  
  <p>This results in the output of </p>

  <p>This should be fairly basic, but clearly, I'm missing something. </p>
