Description:
------------
When reading an HTTP PUT request's body from php://input PHP hangs.

The Windows Server 2008 R2 runs PHP 5.4.23 on IIS 7.5 using the FastCgiModule.

Test script:
---------------
Dump the following PHP code in a file on a server.

<?php
	// Allow from any origin
    if (isset($_SERVER['HTTP_ORIGIN'])) {
        header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
        header('Access-Control-Allow-Credentials: true');
        header('Access-Control-Max-Age: 86400');    // cache for 1 day
    }

    // Access-Control headers are received during OPTIONS requests
    if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

        if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
            header("Access-Control-Allow-Methods: PUT, GET, POST, OPTIONS");         

        if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
            header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

        exit(0);
    }

   $inpData = file_get_contents('php://input');
   
   echo($inpData);
   
   echo("Done");
?>

Then test using this JSFiddle and change the location of the PHP file it PUTS vs POSTS to.

Expected result:
----------------
When running the test above, the result of a POST request will be "testDone" without quotes. The result of a PUT request should be the same.

Actual result:
--------------
A POST request results in the expected behavior. A PUT request should be the same, but times out. It will display "timeout" without quotes.
