Also if output stream is backed by a SocketChannel configured non-blocking then FC::transferTo may return 0 so I assume there is a potential infinite loop there too. I suspect the eventually patch will need have to make use of the blockingLock to prevent the underlying channels from being changed to non-blocking during the transfer.

I need to confess that my NIO knowledge is not deep enough to follow you closely, so I trust on your advice how to go on from here.
