When I asked, it was based on my use of Arduino IDE where one writes higher level code that then gets compiled into machine code. I had a project where I was using multiple sensors where I could not store each of their responses in memory to write to a log in one shot. Instead, I had to write to the log after reading each sensor directly and releasing the memory at the end of each loop. I was originally hoping to do more analysis with the data onboard the Arduino, but in hindsight, that was a pretty dumb idea. The sensing platform should do just that. Do the analysis in post.
