It just occurred to me that the term "streaming" is ambiguous. When we
talk about streaming parsers there are two interpretations:

   1. The parser will read from an input stream and deliver the results
      in a DOM (or via a builder design pattern like SAX-style events.)
      The parser may block while waiting for the next data on the input
   2. The parser only returns the next element, so you have to put a loop
      around it to get a full parse. This is the StAX-style parsing [1].

When I mentioned that protoc is a streaming parser, I was thinking about
the second category, whereas the stream archives belong to the first
category, so I see the confusion now.

I am going to change my vocabulary accordingly and refer to the second
category as pull parsers from now on.
