You can make a user-space scheduler and run a 100000 tasklets on a
threadpool. But there is a GIL in stackless as well.
Nobody wants 100000 OS threads, not with Python, not with Go, not with
Also note that Windows has native support for "taskelets", regardless
of language. They are called "fibers" (as opposed to "threads") and
are created using the CreateFiber system call. I would not be
surprised if Unix'es has this as well. We do not need Stackless for
light-weight threads. We can just take Python's threading modules' C
code and replace CreateThread with CreateFiber.
