I wrote too quickly, based on observation.  But looking at the source code and
"man fflush", the issue seems to be really that fflush() only flushes the output
buffers, not the input buffers, whereas streamio.py will "flush" the input
buffers too and do a small seek backward to compensate.  I think that we should
just kill this behavior, unless there are interesting counter-examples for why
we should not.
