Thanks. I'm aware of asio's synchronous operation support. However, the
application in question implements a producer/consumer pattern, with
potentially many blocking consumers at the same time in the same
application. Other work should be done while "blocking", to keep as many
threads as possible going. Why is run_one better than poll_one in this
case?

Thanks,
Kind regards,
