Description:
------------
I'm playing with Socket support in PHP 5, and found something weird.

I was writing my own classess for Socket support and done a base:
1) create serversocket
2) create clientsocket on serversocket->accept()
3) close clientsocket
4) close serversocket

but if between point 2 and 3 there was no read/write for socket, next try to start a program ended an error.

Below here is a part of code for server (from php documentation).
I just removed everything between socket_accept and socket_close() and added a counter to skip from loop after 3 connections.

Reproduce code:
---------------
$inc=0;
do {
   if (($msgsock = socket_accept($sock)) < 0) {
       echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
       break;
   }

   socket_close($msgsock);
   $inc++;
   
   
} while ($inc<3);

Expected result:
----------------
Program should close all used sockets and run for the second time normally.

Actual result:
--------------
Running example from php documentation with the msgsocket part switched with provieded example for the second time results in 

Warning: socket_bind(): unable to bind address [98]: Address already in use in /server/www/data/thot/tests/simple-server.php on line 19
