Description:
------------
I was using php 4.2.2 before updating to 4.3.3.
I have to talk to another application server using socket.
With 4.2.2, i had my response in less than a second but it take me about 60 sec with php 4.3.3



Reproduce code:
---------------
function getFromSocket($message){
  set_time_limit (0);	
	$res = @fsockopen ("192.168.10.5", "3734", $errno, $errstr,30);
	if(!$res)	{						
		exit; //some eror...
	}
	else{	
	fputs($res, $message);   
//samething, reponding server end the response by SCKEND
// while (substr_count($buff, "SCKEND")!= 1) 
   while ($bytes != "0"){      
      $buff .= fgets($res,4096);
      //$array_statusSocket = socket_get_status($res); //for 4.2.2
      $array_statusSocket = stream_get_meta_data($res); 
      $bytes = $array_statusSocket["unread_bytes"];      
    }
    fclose ($res);
	}
	return $buff;
}
function getMicrotime(){
	list($usec, $sec) = explode(" ",microtime());
	return ((float)$usec + (float)$sec);
}
$time_requete = getMicrotime();
$str_resultatSocket = getFromSocket("LOG|novojustice|justicenovo|intranet||SCKEND");
$time_requete2 = getMicrotime();
echo $time_requete2-$time_requete ." time<hr>";
exit;

Expected result:
----------------
have the result more quickly

Actual result:
--------------
took about 60sec..
