> If you think select isn't broken, show me a small server written using it that can handle more than 1024 concurrent clients. Divide your FDs into groups of 1024 each. Put each group in a different worker thread, each connected to the main thread with a Unix socket. Select over the group in each worker thread; when a socket wakes up, notify the main thread. Select over the worker connections in the main thread. You laugh, but it's a documented approach on Windows [1].
