title: HPPC DoubleOpenHashSet Clear() Method
body: <p>I'm using the HPPC package and I had a question.  In the <a href="http://labs.carrotsearch.com/download/hppc/0.5.4/api/" rel="nofollow">API</a> it says the following for the DoubleOpenHashSet.clear() method:</p>
  
  <pre><code>Removes all elements from this collection.
  Does not release internal buffers.
  </code></pre>
  
  <p>What exactly does the second line imply?  Does that mean that the cleared elements won't be garbage collected?  (I need them to be garbage collected)</p>
