AsynchronousByteChannel and scatter/gather

[David M. Lloyd]

I've noticed that AsynchronousByteChannel doesn't support scatter/gather 
operations; yet the most of the channels that implement this interface have 
scatter/gather operations.  Is there any plan to provide a 
scatter/gather-capable version of the interface?  Or merge those methods 
onto the base interface?

Also, I see that Pipes do not support the asynchronous operation at all. 
Any particular reason?
