You mean we could cooperate on redisigning your library? That would
be great!

I think it can be done by providing a special input-only buffering
transformer that remembers the position at the point of the last
"fill" operation. If you want to discard the buffer, you can simply
seek to the remembered position. This should work well unless the
content of the file changes.
