Description:
------------
I'm creating an IRC Bot, with plugins. All my Plugins are classes, so if you made a change to your plugin, you hadd to restart to complete bot, to reload all plugins. But then I met runkit, and it would be the perfect solution.

But, when I ry to reload all my plugins using Runkit, runkit_import returns true, but the classes aren't reloaded. (When I started the bot through the PHP CLI)

Runkit did actually work when I started the bot through my browser.

Reproduce code:
---------------
	public function reload_plugins()
	{
		// Check for runkit extension
		if(!extension_loaded('runkit'))
		{
			// Try to load it
			@dl('runkit');
			if(!extension_loaded('runkit'))
			{
				throw new Exception('Runkit extension not installed!');
			}
		}

		// Loop through all plugins
		foreach($this -> plugins as $name => $instance)
		{
			if(runkit_import($this ->plugin_dir . $name.'/plugin.php', RUNKIT_IMPORT_OVERRIDE | RUNKIT_IMPORT_CLASSES))
			{
				$this -> logger -> add($name.' Succesfully reloaded', IrcEvent::Other);
			}
		}
	}

Expected result:
----------------
Classes are reloaded, without have to restart my bot.

Actual result:
--------------
On the PHP CLI, the classes aren't reloaded.
