boost::thread and the easiest path to that was to go with the 1.48 Boost release
in the 3P tree (eliminating a fork for a modified 1.45 packaging).  One unit test,
the most important one, is failing in test_httprequest but that can be attended
to later.  This test issues a GET to http://localhost:2/ and that is hitting the
wire but the libcurl plumbing isn't delivering the failure, only the eventual
timeout.  An unexpected change in behavior.

actual problem but this will quiet the compiler.

The unit/integration tests don't work yet as I'm still battling cmake/autobuild
as usual but first milestone passed.
