> To benefit from zero copy we must delegate the file transferring to FileChannel#transferTo(long,
long, java.nio.channels.WritableByteChannel) because the fast path of transferTo method is
only executed if the destination buffer inherits from an internal JDK class.
> The {{CommunicationSpi}} needs to support pipe connections between two nodes;
> * The WritableByteChannel needs to be accessed on the supplier side;
> * The ReadableByteChannel needs to be read on the demander side;
> * The CommunicationListener must be extended to respond on new incoming pipe connections;
