[boost] thread API

Hello, I have axamined the thread_dev header file. Unfortunately the cpp file doesn't seem to correspond. I must admit that the proposed change is a great improvement and removes many objections I had regarding boost thread. Changing the thread object into a handle allows now to copy it. It is then possible to add a thread member variable to a class. A start method can then assign the started thread instance to it. So the gap between boost threads and start&run model gets narrow. The source is one year old. What is the time plan to release it ? -- Bien cordialement, Ch. Meessen
