Linux Kernel 2.6，listen(5)，永不 accept，到底能建立成功多少个连接？

listen(2)
NOTES:
...
The  behavior  of  the  backlog argument on TCP sockets changed with Linux 2.2.  Now it specifies the queue length for completely established sockets waiting to be accepted, instead of the number of incomplete connection requests.  The maximum length of the queue for incomplete sockets can  be  set using  /proc/sys/net/ipv4/tcp_max_syn_backlog.   When  syncookies  are  enabled  there is no logical maximum length and this setting is ignored.  See tcp(7) for more information.

    看系统参数，
/proc/sys/下的net和ipv4中的 有限制最大长度的
超过限制就丢弃
