     I can take care of this, sure.

     Personally I find this profile mode really interesting and would 
advise anyone using libstdc++ to give it a try. I think it worth the 
maintenance effort.

     And today I even consider extending it for an other purpose. I am 
working on using the hint of the unordered insert or emplace_hint 
methods. We will have to document how we use it but I also want to use 
the profile mode to study if the iterator used as a hint has been really 
useful or not. That is part of the nice stuff the profile mode can do.
