Let us clear the your plan.
Maybe we have several tasks.
(1) lightweight fiber switching by pointer-exchange
(w/o copying context).
(2) auto-fiber swiching
(2-1) implement with epoll/kqueue/select
(2-2) design APIs to use it
(3) Implement GVL with futex (in your comment)
(4) Re-implement Queue (some days ago you wrote)
(please add your plan if you have others)
Do you have a schedule? (priority?)
