I have been working on a patch for this issue. I've implemented everything except for readline(), readlines() and the iterator protocol.

In the existing implementation, the reading methods seem to interact weirdly - iternext() uses a readahead buffer, while none of the other methods do. Does anyone know if there's a reason for this? I was planning on having all the reading methods use a common buffer, which should allow free mixing of read methods and iteration.

Looking at issue8397, I'm guessing it would be fine, but I wanted to double-check in case there's a quirk of the iteration protocol that I've overlooked, or something like that.
