Re: [boost] Which libs need multithreading?

I'm tempted to just build single/multi thread variants of all libs just like the default build, but my question is, for which libs does multi-threading actually matter? Is there a subset of boost libs that actually change behavior with this switch? I'd like to get a minimal set.

Looks like regex and serialisation depend on BOOST_HAS_THREADS, but shared_ptr does as well, which means date_time, filesystem, iostreams, program_options, python, spirit, test, and wave as well. John.
