Summary: vars(obj) returns PyStringMap instead of DictType

Initial Comment:
When getting an object's __dict__, the type() of the  
dictionary object returns PyStringMap. This causes a  
problem because types.DictType does not match  
PyStringMap. Some existing Marshallers (in my case,  
xmlrpclib) expect an Instance's __dict__ to be a DictType  
when marshalling an Instance (such as an Exception).  
  
It looks like types.DictType should match  
org.python.core.PyStringMap. When getting the __dict__  
of an Instance in CPython, it returns a type of DictType.

its possible that this could be fixed by just ditching the PyStringMap
used internally and switching over to PyDictionary.  From experimenting
with gutting PyStringMap and replacing its internal arrays and hashing with
a HashMap, I was able to get an increase in performance.  Given that the
Dictionary appears remarkable similiar to that implementation--->
forwarding to its Hashtable(yuck), there may not be a performance reason to
stick with the PyStringMap(assuming that is the reason that there is a
PyStringMap).
