The next release will clean up TLS right after the thread function exits, but that doesn't work for threads that aren't created by Boost.Threads. If that's good enough for you, good! However, if you need TLS cleanup for threads not created by Boost.Threads, the DLL_THREAD_DETACH or some other approach is still necessary.
As I pointed out in another posting: DLL_THREAD_DETACH might already be too late for cleanup. You are relying on the fact that the c-runtime (with respect to this very thread) is still in a sane state! In fact it might not since the runtimes own detach functions already have been called at this time. (Happens within _endthread). So I think doing the cleanup after a boost thread has ended is very reasonable. Nevertheless I am currently trying to accomplish the very same functionality by transparently "hooking" _endthread to call the cleanup code. This way some of the orthogonality is given back, since it is most likely that other threads are based on _beginthread _endthread at minimum (These are required to work with the C-Run time). Going this way would only preclude using native threads, which I consider beeing a minor nuisance. Roland
