Comment:
I think length-prefixed messages would be a lot more useful than
line-delimited messages. Sentinel terminators, especially newlines, are more
error prone to generate and parse than a few bytes of length prefix followed
by a message, repeat.

In addition, the ability to send blobs with newlines is a big win in terms of
the messages that are easily able to be sent across the transport, as well as
giving the developer the ability to improve the readability of the protocol
which is being sent over the wire, as examined in a packet sniffer.
