Go-Flavored Concurrency in C

# Summary Go's lightweight goroutines and channels provide an appealing concurrency model that's difficult to replicate in C, where only heavier OS threads are available. Anton Zhiyanov explores whether POSIX threads can approximate Go-style concurrency in Solod (So), a strict Go subset that compiles to plain C, building a concurrency stack around pthread mutexes and condition variables. He concludes that while native OS threads can't match goroutines' efficiency, a pthread-based approach can offer considerable functionality if developers accept its performance tradeoffs.
