"A fiber is a unit of execution that must be manually scheduled by the
application [do you really want and/or capable of that?]. Fibers run in
the context of the threads that schedule them [correct]. Each thread can
schedule multiple fibers [correct]. In general, fibers do not provide
advantages over a well-designed multithreaded application [that's
right]. However, using fibers can make it easier to port applications
that were designed to schedule their own threads [i.e. archaic academic
coroutines apps]." Welcome back to the past.
