“Despite the fact that implicit coroutines
masquerade under many different names, many of
which don’t include the word “thread” – for
example, “greenlets”, “coroutines”, “fibers”, “tasks”
– green or lightweight threads are indeed threads
… In the long run, when you build a system that
relies upon them, you eventually have all the
pitfalls and dangers of full-blown preemptive
threads.”
