Oh, so the threads are short-lived then. In that case, you should create a pool of them and have each thread "check out" the socket from the pool when it needs to use it and check it back in again when the thread exits. If the pool is protected by a mechanism (like a mutex) that employs a full memory barrier, then it will be safe.
