Wouldn't that mean delay_fn needs to be exposed in the header file too?
I like the fact that it's static and scoped to this file.

Do you mean in the header file or in this file?

I think it won't work because there actually needs to be a __delay
symbol and it can't just be inlined away at all the call sites.
