hash() returning the same value as id() as fallback default is not a 
reasonable assumption. I'm about to fix the long standing broken id in 
Jython and keeping the default hash() equal to id() is a too expensive option.

I even think that in the long run id() should be depracated in favor of 
offering identity mappings and weak identity mappings. id() is not 
reasonably implementable across the range of GC implementations.
