+Even without `--hotreload`, handler changes take effect naturally: HTTP
+requests fork fresh and load handlers on demand, so the next request gets the
+new file. WebSocket connections and rooms keep the old code for their lifetime
+— new connections pick up the change. A natural rolling deploy with no
+interruption. The `--hotreload` flag adds automatic restart for class and
+config changes, which are preloaded in the parent process.
+
+If `Q.handlers.preload` is `true` (production mode), handlers are also loaded
+in the parent — use `--reload` to pick up handler changes in that case.
