Description:
------------
I Can't remove .res file after using ResourceBundle, the only way to remove it, it's to stop apache.

after run this following code, try to delete the .res file

Test script:
---------------
$res = 'http://svn.php.net/repository/php/php-src/tags/php_5_3_5/ext/intl/tests/_files/resourcebundle/root.res';
$file = basename($res);

if(!file_exists($file))
{
    copy($res, basename($res));
}

$r = new ResourceBundle( 'en_US', realpath(__DIR__));
echo $r->get('teststring');

unset($r);

unlink($file);

Expected result:
----------------
Hello World!

Actual result:
--------------
Warning: unlink(root.res): Permission denied in C:\www\test\index.php on line 16
