title: C++ memory cleanup on mac
body: <p>I have C++ code on a Mac that looks something like this:</p>
  
  <pre><code>Object* objectArray = new Object[1000];
  // do some stuff...
  delete[] objectArray;
  </code></pre>
  
  <p>Now it compiles great, and runs great</p>
  
  <p>However, when I look at the Activity Monitor for the process, I find that I allocate 250MB that then do not become available again even after I execute the <code>delete[]</code> statement. Is there a way to make that memory available again without quitting the C++ application?</p>
