Yep, sort of an odd case. Because it is a new component, TR2 would seem the 
logical choice. But with three independent implementations (Boost, 
Dinkumware, and Metrowerks), existing practice is already considerable and 
many LWG members are already familiar with Boost.Threads. The Evolution 
Working Group is apparently also interested in pushing forward with threads 
for C++0x. Hans Boehm and others are working on core language changes to 
legitimize C++ threading and other forms of concurrent programming.
