With the current Boost.Thread interface, I don't see how I can get it either from the current thread or from the thread::id. Can I?
No, you can't get a pointer or reference to the boost::thread object for a thread from its ID. Firstly, there may not be one (e.g. the initial thread, or a detached thread), and secondly that would defeat the point of the separation. A boost::thread instance is a single-ownership object. In general it is not safe to access it from multiple threads. On the other hand, boost::thread::id values are just values, and can be freely copied around.
Finally, if you move your thread between boost::thread objects, all your pointers would become invalid.
If a boost::thread instance is a single-ownership object, what about thread::group? Is the ownership of the thread added to a group transfered to the group? No, I don't think so. In which cases it is not safe to access it from multiple threads? Well even if you are right and the thread pointer was not a good idea, as what I want is to interrupt a thread for which I have a thread::id may be you can add a static function void interrupt(thread::id); Is this function unsafe?
