Description:
------------
There seems to no way to abort a soap call when the response is chunked and none of the chunks exceed the timeout specified with ini_set('default_socket_timeout', 3).

Reproduce code:
---------------
###### File: client.php
ini_set('default_socket_timeout', 3);
$client = new SoapClient(NULL,
    array(
	    "location" => "http://foobar.dk/soap/server.php", "uri" => "urn:xmethods-delayed-quotes", "style" => SOAP_RPC, "use" => SOAP_ENCODED, "trace" => 1, "connection_timeout" => 3
    )
);
$response = ' [NO RESPONSE] ';
try {
	$response = $client->__call(
	    "getQuote",
	    array(new SoapParam("ibm", "symbol")),
	    array("uri" => "urn:xmethods-delayed-quotes", "soapaction" => "urn:xmethods-delayed-quotes#getQuote")
	);
} catch(Exception $e) {	print "Exception: " . $e->getMessage(); }
print $response;

###### File: server.php
<?php
	print '<?xml version="1.0" encoding="UTF-8"?>';
	for ($i=0; $i<20; $i++) {
		print "<!-- $i -->";
		flush(); // The client will wait 20 seconds for the response. Without flush the client will drop the request after 3 seconds.
		sleep(1);
	}
?>

                </ns1:getQuoteResponse>
        </SOAP-ENV:Body>
</SOAP-ENV:Envelope>


Expected result:
----------------
The call duration should be about 3 seconds.

Actual result:
--------------
The actual call duration is 20 seconds.
