For child processes, not really: you can even do the dup()ing only after fork() if you manually clear the close-on-exec flag. So you don't need any extra FDs if you do it 'just right'. Besides, with epoll() and a proper ulimit setup, you virtually have no limit on # connections these days anyway. -Christian
