title: should we forcefully unload a model loaded via loadModel()
body: <p>Is there a function like unloadModel in cakePHP that should be called to unload a model that was loaded using loadModel() function?</p>
  
  <p>I found an unload method,</p>
  
  <p><a href="http://api20.cakephp.org/file/Cake/Model/BehaviorCollection.php#method-BehaviorCollectionunload" rel="nofollow">http://api20.cakephp.org/file/Cake/Model/BehaviorCollection.php#method-BehaviorCollectionunload</a></p>
  
  <p>But it seems to be used for Behavior. Im new to cake. Is there a function like that or does it get automatically unloaded when the called action loses scope?</p>
  
  <p>One more doubt; is using loadModel against MVC's normal conventions? Does it have any adverse effects?</p>
