I haven't read the entire thread, but I was puzzled by the implementation
approach. Did you consider kjbuckets for the standard Python distribution?
While the claim is rather old, the following quote from Aaron's intro  to
the module suggests it might improve performance:
For suitably large compute intensive uses these types should provide up to
an order of magnitude speedup versus an implementation that uses analogous
operations implemented directly in Python.
Adding the gadfly SQL database to the standard library would also be useful,
but since it is back under development it would be best for gadfly to live on
a separate release cycle. The kjbuckets software, however, doesn't seem to
One more reason for adding kjbuckets, Tim Berner-Lee might find the kjGraphs
class useful for the semantic web work.
