Description:
------------
Multiple calls from a PHP-based SOAPClient to a PHP-based SOAPServer 
fail. When you make even two using the same client handle, the call 
fails with the error: 

PHP Warning:  SoapClient::__doRequest(): 7168 bytes of buffered data 
lost during stream conversion! 




Reproduce code:
---------------
THE SERVER CODE

$GLOBALS['HTTP_RAW_POST_DATA'] = file_get_contents("php://input");
ini_set("soap.wsdl_cache_enabled", 0);

$s = new SoapServer('MyWS.wsdl');
$s->setClass('ClientService');
$s->handle();

CLIENT CLODE

ini_set("soap.wsdl_cache_enabled", 0);

$client = new SoapClient('MyWS.wsdl', array("classmap"=>array("NewClient"=>"NewClient")));

$result = $client->getNewClient();
//SECOND CALL CREATES WARNING
$result = $client->getNewClient();
		
		


Expected result:
----------------
The script should run with no errors or warnings.

Actual result:
--------------
PHP Warning:  SoapClient::__doRequest(): 7168 bytes of buffered data 
lost during stream conversion! in /Users/../test.php
