title: Do messages sent via Netty's Channel.write() preserve their order when begin sent out to the network?
body: <p>I am doing some sort of encryption which depends of the order of messages sent via a Netty channel. What I am expecting is that if I write message A before message B to a channel then they should be sent to the remote socket in the same order I have written them to the channel. So is the case I need already supported by Netty?</p>
  
  <p>On the other hand Netty's Channel accepts concurrent write calls and I am in doubt my requirement can already met. I had to synchronize on a statefull (a per channel one) encoder today due to currupt state of a data structure. However I am still not sure whether the in-filter synchronization will help my need.</p>
