DESCRIPTION
       WARNING: select() can monitor only file descriptors  numbers  that  are
       less  than  FD_SETSIZE (1024)—an unreasonably low limit for many modern
       applications—and this limitation will not change.  All modern  applica‐
       tions  should instead use poll(2) or epoll(7), which do not suffer this
       limitation.
