Bug description:  fsockopen will not work on 'localhost'

Description:
------------
If I use fsockopen with host 'localhost' it fails, but it works with
'127.0.0.1' or any other host name.

Reproduce code:
---------------
function connect($host) {
    $faultcode   = null;
    $faultstring = null;
    $conn = fsockopen($host, 80, $faultcode, $faultstring, 20);
    if (!$conn) {
    	echo 'faultcode=' .$faultcode .', faultstring=' .$faultstring
."\n";
    } else {
        echo "Connected to $host OK\n";
    } // if
    return $conn;
} // function

$result = connect('localhost');
$result = connect('127.0.0.1');
$result = connect('desktop');
$result = connect('www.tonymarston.net');

Expected result:
----------------
I expect to see the message "Connected to <host> OK" for all values of
host.

Actual result:
--------------
Warning:  fsockopen(): unable to connect to localhost:80
faultcode=10060, faultstring=A connection attempt failed because the
connected party did not properly respond after a period of time, or
established connection failed because connected host has failed to
respond.

Connected to 127.0.0.1 OK
Connected to desktop OK
Connected to www.tonymarston.net OK
