that's why, for instance i was pursuing the idea of implementing process
scheduling in a language itself, leaving very small part of required logic
on VM side
- mostly stripping a logic that switches process(es) to specially
registered 'interrupt' process, when signal from semaphore arrived, while
leaving the rest of logic on hands
of image-side implementation.
