Even with GOMAXPROCS=1, a Go program is not 100% deterministic. See this funny blog post on how to gain randomness even without using the standard library. https://blog.merovius.de/2018/01/15/generating_entropy_without_imports_in_go.html Using libs, there are even more sources of indeterminism, e.g. time.Now() or both of the "rand" packages.
