If you guess a wrong address, the process crashes. With a fork-based server, you don't care much about that. Every time you connect, you get a fresh new process - with the same addresses as the older copies even. So brute-forcing those is more viable than a browser where you probably won't have more than 1 or 2 attempts per user.
