yes POSIX threads, i.e. user-space threads I think you have a very strange definition of "user-space", "kernel-space". kernel space is what runs _in_ the kernel, it doesn't involve pthreads (on any OS) and uses kthr

Concepts of cooperate multi threading, co-rutines etc. aren't limited to user space. Actually they out date the whole "async" movement or whatever you want to call it. Also the article is about user-space threads, i.e. OS th

If your threads run "cooperative multi threading" task (e.g. rust tokio runtime, JS in general etc.) then this kinda is a non problem. Due to task frequently returning to the scheduler the scheduler can do "should stop"
