On Windows yes (though StackWalk64 is slow too, I see you or 
someone else has already fixed that on git), but on Linux it 
constructed the full string in the constructor!

I have a pull request pending some minor details to be worked out 
that will fix that. Gives a 20-80x improvement on thrown then 
caught exceptions without printing them.
