[Boost-users] Intrusive unordered set and thread safety

Hi, I have been playing around with the boost intrusive unordered set. If my application is multi-threaded I do not see any way to make the set thread safe at a bucket level. I have seen a previous post from November 2012 "[Intrusive] unordered_set and thread safety" which asked the same question. At that point it was not implemented but I have not seen any updates in that area since. My question is, has it been implemented or is there a plan to implement such a feature in the near future? Thank you, Dave.
