Here where? The GNU libstdc++-v3 implementation? Certainly we did, as I 
tried to tell you the issue - the tradeoff between a more "correct", 
simpler, and certainly easier to synchronize implementation and better 
performance in some cases - isn't new. Please carry out a through search 
of Bugzilla and mailing list, there must be something recorded. I'll see 
if I can help about that, it's been a while.

Paolo.
