In fs/select.c version 2.2.14 there is a comment in sys_select...

        /*
         * We ought to optimise the n=0 case - it is used enough..
         */
         
        if (n < 0)
                goto out_nofds;
        if (n > current->files->max_fdset)
                n = current->files->max_fdset;
                

but this comment is gone in 2.3.99pre2. would this no longer be
a useful optimization?
