Hi Branimir,

I will retain exactly the same copyright it had. To get rid of the old
copyright, you'd need to clean-room re-implement it (you yell ideas
from another room and somebody implements them in Haskell not having
seen the CPP code beforehand).

This is normal. You trade performance for the ability to pre-empt
(e.g., not get stuck on blocking FFI).

Kind regards,
