[boost] [boost.thread] ReadWrite Locks

hello! until boost 1.33.0 there was in the lib(boost thread) the RW locks, now in 1.33.1 is off for deadlock reasons as I know... what about the next version of boost(1.33.2(??)),it would have it again? in the sandbox there is something... does somebody know when the next version will be ready?? I am working on a project and I wanna use RW locks,I dont want to use 1.33.0 RW locks not becouse I am afraid of deadlock,the use of them will be simple,but becouse I want to use the latest stable vesrion. thanks!
