this is classic with silly window syndrome, and there are specific 
mechanisms in TCP implementations to avoid that. In short, TCP doesn't send 
partial segments unless triggered in some way, such as no longer having 
anything outstanding (Nagle's algorithm) or getting an API "push" event.

But that said, these events do indeed happen, and reordering happens in 
such cases.
