Here's a horrible workaround:

	extension DispatchQueue {
		class var currentLabel: String {
			return String(validatingUTF8: __dispatch_queue_get_label(nil)) 
		}
	}

But I think this is a hole in the current design. I'm not sure if it's an *intentional* hole or not; the concept of a "current queue" in general is a bit squirrelly.
