* pthread_key_create and pthread_key_delete now manages correctly a list of key/destructor * pthread_create now uses a private thread function to add a "on_exit_thread" call for destructors * pthread_join now returns B_OK in every case, and, as a joinable thread could already be gone, wait_for_thread would not find it git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17895 a95241bf-73f2-0310-859d-f6bbb57e9c96
