It doesn't need Boost.System, but it does still depend on a few pieces
of boost that we're not currently using, notably
boost::date_time::posix_time, bleah.

Yeah, there's not much of an alternative there unless you want to
implement your own DNS resolver, which isn't a good idea.  [Linux does
have getaddrinfo_a, but it's not portable, it may still use threads
under the hood, and it reports completion with *signals*.  Gag.]

That was one of my goals, in fact.  We may not be 100% of the way
there yet though.
