Very high CPU usage using pnpm

Maybe I’ve done something wrong but even with the dumbest config ever I feel like I have an error while running nollup in order to get HMR working for my CSS and Javascript.

I always get this output in the terminal whatever config I’m using (tried many, from some other repos, etc). The only way for me to get it working is by using the examples as it from the examples folder of this repo, which calls the cli from a javascript file. When I try to use the nollup -c command, that’s when issues are coming by.

> npm run dev

> test-nollup@1.0.0 dev /Users/user/Desktop/Rollup
> nollup -c --hot --port 3000

Also the node process in my Activity monitor goes off the roof with at least 300% CPU.

Am I missing something ? 🤪
