[boost] [unordered] status update?

I was wondering what the current status of unordered was. I don't see it scheduled for review so I assume none has yet been requested? I'd particularly like to see this make it into boost::tr1 if accepted. Needless to say this is a very important library. I notice recent changes in boost sandbox so I'd appreciate an update on intent from Daniel ( if you have the time ;) ). Thanks, Jamie
