Description:
------------
This request related to bug for previous version of PHP 
(http://bugs.php.net/bug.php?id=51815), but as i found i have same issue on php 
5.3.6.
Libcurl have  options as CURLOPT_MAX_RECV_SPEED_LARGE and 
CURLOPT_MAX_SEND_SPEED_LARGE, but seems them didn't work at current stable 
version. to reproduce the problem i use same script as in previous bug report.
 

Test script:
---------------
<?php

// create a new cURL resource
$ch = curl_init();

$fh = fopen("out.dat", "w");

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_MAX_RECV_SPEED_LARGE, 10240);
curl_setopt($ch, CURLOPT_URL, "http://bitcast-a.bitgravity.com/bitgravity/1MB");
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
fclose($fh);
?>


Expected result:
----------------
Script should download the link with approximate speed as 10kb/s and took around 
seconds...

Actual result:
--------------
Script download file with full speed which available for my connection, i.e. no 
any rate limit was assigned to curl task.
