I'm not sure what counts as major, but I guess most of the issues I raised
for Boost.Iostreams probably aren't (given the lack of replies to my
previous mail: http://tinyurl.com/mah8f)?

IMHO the significant performance problem I reported then for streams on
Seekable Indirect Devices *is* a big issue.

Is anyone else interested in this issue (or any of the others) and/or
reviewing my patch (it maybe too simplistic to cover all use-cases)?

FWIW, in a real world test case, using

* stream<file_descriptor> (from 1.33.1) resulted in total read bytes of ~250
MB
* std::fstream resulted in total read bytes of ~8 MB
* patched indirect_streambuf resulted in total read byte of ~8 MB

Thanks,
Gareth
