[boost] [chrono] [thread] Incorporating Chrono into Boost.Thread implementation

During the review of the Boost.Chrono library and earlier, there was some discussion about how Boost.Thread might adopt the Chrono-based interfaces once Chrono was formally accepted and merged into the trunk. I believe that Vicente even had proposed code for some of the possible changes. Now that Ratio and Chrono are officially part of Boost, is there still an intention to do this? If so, is there any timeline for when these Boost.Thread changes might begin appearing in the trunk? I know this depends on Anthony and others' availability, but I was just curious. Thanks, -Dave
