Those examples are wrong. `io_context` should be passed by reference.

A smart pointer is less efficient than a pointer, all else equal. But
you shouldn't be using any form of pointer, the io_context (legacy
name: io_service) is passed by reference. All of the Beast and Asio
examples demonstrate this:
