   public CommQueue() 

Default constructor

   public void enqueue(CommSpaceElement elem) 

XXX implicit allocation in elements.addElement().

   private static CommSpaceElement copy(CommSpaceElement e) 

XXX is it necessary to copy the CommSpaceElement out of the CommSpace??

   public CommSpaceElement waitToTake()  throws InterruptedException

XXX implicit allocation in elements.removeElementAt() (downsizing).

May throw InterruptedException if the wait() is interrupted. The caller will have to restart the waitToTake().
