Indeed.
The future style is really an alternative to the
InputSource/OutputSink methods that allow enquiries about completion.
The style of passing in a completion handler for a specific IO
operation is an alternative to registering a listener for IO events.
I think there is merit in considering an API that is as close to both
java7 styles as possible - even though both require preallocation of
buffers (perhaps that is also fixable).
