C++ 11 threading API: is there a free implementation for MSVC 2010?

Question

Is there any free 3rd-party implementation of std::thread API for use in MSVC versions older than 11?

Answer 1

My just::thread library provides a complete implementation of the C++11 thread library for MSVC 2005, 2008 and 2010, including std::thread and std::async, but it's not free. For a free implementation the closest you can get with MSVC is boost, but there are a few differences.
