I implemented a 1:M:N userspace lightweight thread scheduler which has 3 types of threads. 1 scheduler thread, M kernel threads and N lightweight threads. The scheduler preempts the kernel threads and lightweight threads to switch processing between them and uses timeslices. I wonder if I can integrate coroutine support as I'm not sure what the difference between a coroutine and a lightweight thread is. How does it preempt? I set the for loops and while loops to their limit from the scheduler thread! This ends hot loops! https://github.com/samsquire/preemptible-thread https://github.com/samsquire/preemptible-thread
