I would argue that attempting to hijack a random Go thread to complain about CGo is also off-topic. They can write a coherent article and post that, if they want, but repetitively distracting from the actual thing being discussed is tiring. Also, CGo design is a trade-off, and makes perfect sense. Nobody has come up with a design to have both fast C ABI FFI (no stack/thread switch) and cheap green threads (small stacks). People complaining about CGo rarely seem to understand this.
