It's Critical: Concurrent programming as a sane programming model
summary
Builds a toy async-await framework from generators, non-blocking sockets and the OS selector, implementing futures and tasks and a simple event loop that drives generators with selector events. Shows the code sending about 200 concurrent requests on a single-threaded event loop with no extra OS threads, demonstrating cooperative multitasking, fewer locking needs, and that network I/O interleaves correctly; the handcrafted framework runs and completes the requests.
