Description:
------------
I am running PHP 5.2.0 under Apache 2.0.55 on Windows XP Pro SP2, and using the php_rar.dll found on http://pecl4win.php.net/list.php.

I have created a simple test script to play with this extension.

Reproduce code:
---------------
<?php

$resRar		= rar_open ('/home/public_html/tests/test.rar');
$arrFiles	= rar_list ($resRar);

foreach ($arrFiles as $objFile)
{
	echo 'Filename: ' . $objFile->getName () . '<br />';
	$objFile->extract ('/home/public_html/tests/rar/');
}

if (!rar_close ($resRar))
{
	echo 'Not Closed';
}

unlink ('/home/public_html/tests/test.rar');

?>

Expected result:
----------------
The script is expected to open the rar archive, extract the contents, close the archive and delete it.

Actual result:
--------------
The archive is opened and extracted successfully, but does not seem to be closed correctly despite the use of rar_close.

A "Permission denied" error is returned for the unlink function, and i cannot delete the file through windows until i restart apache.
