nghttpx: Split monolithic one process into control and worker processes The control process handles signals, reads configuration, reads private keys, and bind port (which may be privileged one). It never drop privileges, so that it can execute new binary with the same privilege. It forks worker process. The worker process handles all incoming connections. It drops privilege.
