Actually, the correct behaviour would be to fall back to the
possibly-throwing move if the type is non-copyable, so maybe there's a
problem with the libc++ std::vector, although I'd find that almost as
surprising as a bug in clang's deleted function support.

The boost::thread move ctor should still be noexcept anyway, and that
should solve the problem.
