Overall this looks good to me. Thanks for fixing this!

I just had a few nit-ish comments.

re:having-spin-or-nonblocking-in-fn-name, I added those to make it obvious to spot cases where they might get used in incorrect contexts. For example, using a spin wait for a state inside a lock, which could cause a deadlock because the other side is waiting for that lock, so it can change the state.
