I understand that the real-time thread entrypoint functions will need to do this parameter manipulation - but this entrypoint can be different to the real-time algorithm entrypoint. Here's what I mean:


Ah, yes this makes sense to me! I am good with intercepting then. I agree your "real time setup" functions should not be `nonblocking` constrained generally, as they exist in the primordial soup before you start fielding requests.
