coroutines can be used to manage concurrent tasks on a single thread.

Boost.Asio is one way to manage those tasks with an event loop (simply 
have a single thread running the io_service/io_context); additional work 
can be posted both from "inside" and outside.

Boost.Fiber 
(https://www.boost.org/doc/libs/1_67_0/libs/fiber/doc/html/index.html) 
is another way.  This also supports futures, although not currently 
then-able ones.
