Wow, ok, file was broken on changing position in the stream, it wouldn't reset
the end of stream flag. Now it does reset it, and assumes that you've placed the position not at the end, if you have, it will detect it again immediately upon read. BZip2 now provides a method of getting the number of bytes written out, i.e. the compressed size of the output, I have to figure out the input side next...
