I supposed you are aware if other implementations of the library already including the optimization. I'm looking for some concrete evidence, because you know, vector is deprecated, isn't a real container, and all the well known bad things about it, thus we normally don't do much development work on it beyond ghe basic maintainance. Of course, if you have already a patch, that would definitely speed things up ;)
