As you mentioned, threads are required for the async DNS lookup.

This has never really come up, and to my knowledge you are the
first to ask for the ability to build without using thread
support.

I can check for BOOST_DISABLE_THREADS (in fact I've already made
some changes along this line), but when threads are disabled
functionality like asynchronous host resolution will have to be
made unavailable.
 
Cheers,
Chris
