I know it's just an example, but if you're on linux there's signalfd() which makes signals into IO so you can handle it in an epoll()-loop or whatever way you like doing IO

We can't remove the old way of course, as that would break things, but that doesn't stop improvements

Sometimes removing the old way is the improvement though. E.g. adding an alternative to symlinks doesn't help if symlinks are still allowed.

[chikere232]

Why?

That way you break a lot of things.

You have to start somewhere. Strongly specialized programs that f.ex. never access disk and only access network are a good candidate to be tested in either restricted containers or brand new OS-es that carry legacy baggage.

It's doable, but nobody wants to put in the money, time and energy into pioneering it.
