Each read or write will actually trigger a read or write to the external buffer space allocated for that proxy thread, where the real message data is stored. In addition, when a write message completes, the external buffer will be read for the entire message for that proxy thread so that it can then be written to the target. Similarly, after a read causes a read from the target to get a new message, the entire message is written to the external buffer to store the message to the buffer.
