- Add missing exports to `node:cluster` - Fix default export not being an instance of `EventEmitter` - Fix aliasing of properties - Fix `disconnected` -> `disconnect` export naming This makes `log4js` work in Deno. `karma` starts too, but somehow the server isn't responding. That looks like a different issue. Fixes https://github.com/denoland/deno/issues/24858
