* Maximum number of SYN_RECV sockets in queue per LISTEN socket.
* One SYN_RECV socket costs about 80bytes on a 32bit machine.
* It would be better to replace it with a global counter for all sockets
* but then some measure against one socket starving all other sockets
* would be needed.
*
* The minimum value of it is 128. Experiments with real servers show that
* it is absolutely not enough even at 100conn/sec. 256 cures most
* of problems.
* This value is adjusted to 128 for low memory machines,
* and it will increase in proportion to the memory of machine.
* Note : Dont forget somaxconn that may limit backlog too.
