It seems weird to me that Collin's group can be working so hard just to get a percent or two improvement in specific cases for pickling while python-dev is readily entertaining a patch that slows down the entire language.

I think it's really more than a percent or two: http://bugs.python.org/issue5670

For lists, it was a percent or two: http://bugs.python.org/issue5671

I expect Collin's overall efforts to payoff nicely. I was just pointing-out the contrast between module specific optimization efforts versus anti-optimizations that affect the whole language.
