- the user is responsible that all worker fibers terminate
- dispatcher fiber must run till all worker fiber are terminated and
the the scheduler is shut down
- flag shutdown is set in ~scheduler before resuming the ready fibers
- the ready fibers must contain at least the dispatcher fiber

- unwinding the stack via exception is not always necessary
- usually a fiber returns from its fiber-fn (stack is already unwound)
