After a few days offline for my 30th birthday celebrations and a crappy cold, today I made a small commit to libstdc++, so that GCC 4.3 will have a slightly faster shared_ptr in MT apps. Yay. Bigger shared_ptr improvements to follow now that's out of the way.

I'm also familiarising myself with the forthcoming std::unique_ptr, which is not available in GCC yet (there's an implementation but I think it's waiting on copyright assignment paperwork.) I've now put my foot in my mouth on two mailing lists in threads about deprecating auto_ptr, by moaning about non-issues; I'll try not to do it a third time.
