"attached()" seems a good name to me. Just about every member function
of boost::thread requires that the thread is joinable() for it to have
any meaning.

I've used the same wording for boost::thread::id as well, but clearly
an ID is not joinable(). OTOH, a thread::id could be attached(),
meaning it actually represents a thread rather than "not-a-thread".

Are you going to be at Sophia-Antipolis? It might be worth raising the
same issue wrt std::thread.
