    v70 v71  
    1616 * http://diveintopython.org/performance_tuning/index.html
    1717 * If a specific inner-loop routine cannot be optimised in Python, then consider writing a C routine for this use case.
     18 * If Python is eating too much memory, it could be because you are instantiating lots of a particular class, consider using __slots__ http://stackoverflow.com/questions/472000/python-slots
     19 * You can check the actual memory usage per class using MyClass.__basicsize__, remembering that subclasses of classes without __slots__ or top-level classes without __slots__ have a __dict__ which also takes up memory.
