[Seaside-dev] note on using hash of an object's class....

[Dale Henrichs]

I've just noticed that in GRSmallDictionary>>hash, the hash of the class 
is used for calculating the object's hash and I just wanted to point out 
that that is not portable (at least relative to GemStone).

In GemStone there is the notion of class histories, which means that 
there are multiple versions of a class which means that the hash of a 
class cannot be counted on to be constant for a given class, which means 
that it shouldn't be used in hashes...
