There's a missing include:
#include <boost/thread/thread.hpp>

Perfect, sorry - I should have spotted that one (was too baffled by the code to start with the simple things!).
The simple example above is around 10% slower when run multithreaded compared with a single thread (optimized). This is substantially better than my previous attempts! If reader_thread() were more complex then I guess we would expect an increase in efficiency compared with a single thread.
Thanks very much Anthony and Steven for your help.
