You create a service through the asio executor that contains a
capy::execution_context - and vice versa.
When the corosio::socket then gets the scheduler from this context, the
scheduler *should* create a thread for the reactor.
Then, the completion would do a dispatch back onto the asio executor.

The above isn't clearly defined in capy yet, which is another reason it's
not merged at this point.
