I think I don't understand the difference between an Executor and a 
AsyncChannelGroup.

Furthermore, there is currently no way to use the same Executor for more 
that one
AsyncFileChannel because closing the file channel will shutdown the 
executor.
I don't understand the purpose of this restriction.
