Maybe I drank too much coffee last night, but this is working for me if I
add dirname(__FILE__) to "log.txt" (PHP version 5.2.4) and not otherwise

<?php
session_start();
class a
{
    public $b;

    public function __sleep()
    {
        file_put_contents(dirname(__FILE__)."/log.txt","ok" .
PHP_EOL,FILE_APPEND);
        echo "done!";
        return array();
    }
}

$a = new a;
$_SESSION['obj'] = $a;
?>
