I think you are trying to make a conceptual distinction which doesn't exist in practice. Your OS uses buffers to represent "streams" to you. Also, how come StreamReader has internal members named "bytebuffer", "charbuffer" and "linebuffer"? There certainly seems to be some (non-trivial) amount of buffering going on there, and probably quite slow and inefficient since it's pure Python (TextIOWrapper is written in C).
