/**
 * see WINSOCK2.H, 用户需要预先定义此值，因其默认值为64，此外，该值不能设得太大，
 * 尤其是在 X64 编译时更是如此，参考 fd_set 的结构定义：
 * typedef struct fd_set {
 *   u_int fd_count;
 *   SOCKET  fd_array[FD_SETSIZE];
 * } fd_set;
 * 当在 x64 环境下，当 FD_SETSIZE=50000 时，该结构占的空间大小为：
 * 8 + sizeof(SOCKET) * FD_SETSIZE = 400008
 * 而在 events_select_thr.c 的函数 event_loop 中声明了三个 fd_set 变量，
 * 则该函数其所占用的栈空间大小 > 1MB，而 VC 默认的栈大小为 1MB，则当调用此
 * 函数时就会造成线程栈溢出；
 * 当需要将 FD_SSETSIZE 设得很大时，则需要调整可执行程序的栈空间大小，即在程序
 * 编译链接时的选项中，将“堆栈保留大小”选项设大一些
