Sorry, I don't agree. We assume an imp.load_dynamic function from what  
we read in the python documentation. But the implementation in GAE  
does not provide the expected api. So the NotImplementedError seems  
absolutely correct to me (see http://www.python.org/doc/2.5.2/lib/module-exceptions.html#l2h-114) 
.
