I’m strongly negative about requiring people to avoid newlines in their
JSON in order to be able to string chunks of JSON together into a stream.
 JSON is unambiguously and easily parsable.  To talk in abnf, I don’t think
we should be satisfied with anything less than this:

JSON-sequence = JSON-text *(text-separator JSON-text)
text-separator = 1*(  %x20 / %x09 / %x0A / %x0D )
