Comment(by each):

 >  - for a similar reason, including internal/{tcp,udp}dns.h in
 asiolink_unittest.cc is not good.  btw, if we don't use asio::io_service
 it compiles without these header files, so at least including these
 doesn't make sense.

 IIRC my intention was to add more specific tests of tcpdns.cc and
 udpdns.cc routines, but I didn't make as much progress on testing as I had
 planned (unfortunately TDD went in the tank almost immediately after I
 started this work).

 Probably those tests should still be written and they should include
 tcpdns.h and udpdns.h, but they should live in some other file than
 asiolink_unittest.cc.

 Regarding the asio::io_service interface, I think that came out of the
 original asio_link_unittest.cc from trunk.  I had assumed this was by
 design--the IOService class included a get_io_service() member to give
 access to the underlying implementation.  I don't expect it would be very
 difficult to change this in the test code though.
