When your goal is to show your pet language is 'better', you pick the benchmarks that 'prove' it.

No, this is really the whole point of an RTOS. It can preempt low priority tasks to respond to critical events.

I'm quite clear on what the point of an RTOS is, thank you. But I wasn't addressing that, which is the point you seem to have missed.

True RTOS scheduling is equally possible on Rust. RTIC does it already.
