11. For example, when the operating system's latency and busy-waits by using queuing and context switches . 12. With hundreds of threads, a context switch time of 10ms produces a latency in seconds. 13. Because of that the context switch in the DioneOS system was optimized for short time. 14. Protothreads are also stackless, which means global variables are needed for preserving variables across context switches . 15. It seems to be suggesting that a context switch saves registers on " the stack ". 16. Using this mechanism a different instruction set could be selected each time a context switch occurred. 17. It is expensive to park and unpark a thread, and a slow context switch may occur. 18. Context switches require from microseconds to milliseconds, while the Map's own basic operations normally take nanoseconds.19. Having the scrum master also multitasking may result in too many context switches to be productive. 20. In the case of GHC Haskell, a context switch occurs at the first allocation after a configurable timeout.
