Coroutines is a bit more complex but a library is available. Select-based "threads" aren't too difficult to set up in C, you could use http://www.nightmare.com/medusa, a Python implementation, as a starting point. Also most NNTP servers have been using techniques like this for years. The key to these types of systems is that they don't spend much time per request.
