Similarities to thin threads from JRockit?

Hello everyone involved with project Loom!
First of I’d like to give my support to you guys as the progress you’re making is impressive to say the least and I hold all my thumbs that you’ll be successful in the project.

Could anyone instruct me in how Fibers differ from i.e. thin threads which was implemented in the JRockit VM? Are there similarities and did you reuse any of the experience and learnings from that?
Also, I think a good FAQ/comparison would be helpful as the concurrency terms seems be tossed around causing confusion whenever the Loom project is being discussed.

It would be nice to have one source of truth comparing it against i.e Kotlin coroutines, green threads, go-routines and thin threads. I get that the Kotlin / C# / JS way is i.e. not solving the colored method problem, but it would be nice to have a comparison matrix or something similar for the alternatives.

Best regards and good luck!
