+You need `reloadReturn.wss.close()`, if you want automatic rebuild and restart of server code 
+independently, while preserving a front-end bundle already built by [WebPack](https://webpack.js.org/), for example.
+To make it happen, old _express app_ should be discarded, a new one instantiated and bound to _reload_ again.
+But without closing _wss_ first, an `EADDRINUSE` exception would be thrown.
