Another thought about buffering, which might be a bit of a show-stopper: if in a particular load() call we read ahead for buffering purposes, we've altered the underlying stream (which might not be seekable to allow position restoring). The next call to load() will be likely to fail, since the underlying stream has been positioned further than expected by the earlier load() call, and the buffer state has been lost. Not sure how easy it is to get around this ...
