[ENet-discuss] Only next to last packet out of order?

I suggest attempting to replicate this behavior with using UDP only.
Success should indicate that Enet is not responsible. I assume you
don't expect unreliable packets to be received in any particular
order, and are just curious of this consistent behavior.
