in selectmodule.c, I found the code of epoll module
'        result = epoll_ctl(epfd, op, fd, &ev);
        if (errno == EBADF) {
            /* fd already closed */
            result = 0;
            errno = 0;
        }
'
'man epoll_ctl' show 'EBADF  epfd or fd is not a valid file
descriptor.', assume I register an fd of 'open('xxx', O_RDONLY)', return
value will be -1, errno will be EBADF,  
epoll not support 'file descriptors.' as i know,  or i register an fd
was not be opened.
