I have 2 questions
How will AsynchronousFileChannel work if my operating system does not support AIO (lower then linux 2.6 etc).
How to append sth into AsynchronousFileChannel, as far as I know AsynchronousFileChannel only supports write(ByteBuffer, long position, A attachment, CompletionHandler handler) and write(ByteBuffer src, long position) both need a position param. Should I count the position myself?
