// configuration directives to make a configuration interface

// postconfiguration hook that actually does the work of setting up an event loop
//   - calls ngx_create_listening based on sockaddr and socklen
//   - sets listening->handler (see ngx_http_init_connection)
//   - sets listening->pool_size
//   - sets all this shit (see ngx_http_add_listening)

// listening-> init connection handler
// close connection function for error handling
// set up read event handler for conn->read->handler
// set up write event handler for conn->write->handler
// make a new request obj and set c->data

// figure out how a read is actually done
// figure out how a write is actually done
