If we really use all of the data, then I can't see how processing the
bytes and parsing them can be the dominating factor, so
a `start-json-process` wouldn't make any significant difference.

But at least in your example of semantic highlight we definitely don't
have to use all of the data, but only the portion relevant for the
currently displayed parts of the buffer.
