Let's say I have 1 million promises in my node program that will never return, how does nodejs tell the kernel to handle these asynchronous functions?

I understand that the main event loop is a single thread and that the functions can execute asynchronously. I also heard that the async functions aren't multithreaded but instead scheduled by the Kernel..somehow that i can't really grasp.So I was thinking, if I have a promise that just does an infinite loop before returning a promise (so it never returns the promise and keeps on running), and I have 1 millions of those, how does the kernel and nodejs handle those functions? Will it still execute asyncronously? Will the functions, which are each processes have to share each core?
