In the concrete +example, only a **single** user thread can run at any given time, whereas in +the case of os-level threading, all threads can run truly parallel. + +When a user-level thread is scheduled, the *stack-pointer* (sp) of the os +thread is adjusted to the user threads' stack. For the example below, if the +user thread **A** is scheduled (yielded to), the stack-pointer for the os +thread **S** is switched to the **stack A**. Once the user thread yields back +to the scheduler, the stack-pointer is switched back to **stack S**. + +<img src="os-vs-user-threads.svg"> + [matcha]: https://github.com/johannst/matcha-threads
