If one context ends what should be the standard behaviour?
When the main-context (main function ends) - the app exits.
If you which to jump to the originating context (for instance it may be 
main()) you can link against it and the originating context will 
continue its execution.

look into boost.fiber or boost.task

boost.fiber uses boost.context to implement cooperative scheduling and 
boost.task uses boost.fiber to distribute several tasks on a limited set 
of threads.
