/**
* Represents a transport back-channel.

*
* When the JAX-WS runtime finds out that the request
* {@link Packet} being processed is known not to produce
* a response, it invokes the {@link #close()} method
* to indicate that the transport does not need to keep
* the channel for the response message open.
*
*
* This allows the transport to close down the communication
* channel sooner than wainting for
* {@link PipeHead#process}
* method to return, thereby improving the overall throughput
* of the system.
