This ain't rocket science. You make it sound so simple, but the fact that an environment is set up and torn down for each request is fundamental to the whole language, not just a detail of the engine. If all you're doing is making that setup and teardown quicker, I don't see how you're getting any closer to asynchronous code. FPM could do all sorts of magic with its memory management, but it wouldn't help someone write a WebSocket server. Maybe I'm missing something, but I can't picture how you'd have a meaningfully event-based SAPI that looked just like a single-request one to the user. Regards, -- Rowan Collins [IMSoP]
