Hi Borko,

which version of boost do you use? I'm asking because I very much rely
on iostream::restrict device and never had any issues so far. That is up
to boost 1.41 because we have not moved to a newer version yet.

I find it annoying that nobody ever answers questions related to
boost::iostreams.
