By using the system in a test, we can not just verify things about its behaviour, but also show users how

Go basically never frees heap memory back to the operating system Over on Reddit's r/golang, I ran into an interesting question about Go's memory use as part of this general memory question: [...] However Go is not immediately freeing the memory, at least from htop's perspective.
