> Write and Commit responses directly write data to the channel instead of propagating
it to the next immediate handler in the channel pipeline. 
> Not following Netty channel pipeline model could be problematic. We don't know whether
it could cause any resource leak or performance issue especially the internal pipeline implementation
keeps changing with newer Netty releases.
