Looking at my 'I only do one thing' Pi running 94 different processes,
realistically how many of them do I need? And how could I get rid of them?

I want to examine the pi as a reasonably real-time signal processing unit.

I don't need disk access except to load the code. I may not need network
access. I don't need logging. I sure don't need systemd. I don't need a
gui.

I just want to run one high priority daemon and one lower priority
demon, with shared memory between them...is there something simpler than
Linux? More like e.g. DOS?
