   @wy96f is this really a feature you really would like to have?
   
   - as we moved through this task, we realized the RegionFile is not actually 
doing zero-copy. it's using a ByteBuf just like before.
   
   I bet there's an issue within Wildfly where the execution happens twice, and 
the actual move would happen on a secondary buffer or something...there's a 
loop within xnio capturing packets from HTTP into Netty (Wildfly has a single 
port for everything).
   
   We had a few people working on it this week, this feature is getting lot of 
attention for little benefit.
   
   If you really think this is a nice feature to have.. perhaps you can keep 
going... but as it stands I would say to keep it out!
