Expand description

Repeatedly reads from a TcpStream and carves out messages.

The intended communication pattern is a sequence of (header, message)^* for valid messages, followed by a header for a zero length message indicating the end of stream.

If the stream ends without being shut down, or if reading from the stream fails, the receive thread panics with a message that starts with “timely communication error:” in an attempt to take down the computation and cause the failures to cascade.
