LOR = locality of reference (I'm fairly sure).

Important for caches and things. Though I'd have to say worrying about
cache misses caused by Python's reference counting strikes me as, uh,
not especially productive, though I'd have to admit I'm not really
following every nuance of the discussion (Tim Peters and Vladimir
Marangozov being difficilt to understand in a technical discussion!
Gosh!).

I suppose VM page misses are more important...

Cheers,
