Hernan,
you patches are ok with me. So now you can help yourself and
check-in your changes. Remember to do different commits for
different aspects.
You can also directly commit follow-up changes if you think they
are safe.

I'm not sure about that. But I'm more inclined to do optimizations
only when a profiling tool shows what the bottleneck is (as someone
said: early optimizations are evil)
