To reproduce:

1. Create a new node project with the following code in index.js:
   ```
   const Realm = require("realm");
   const app = new Realm.App( { id: "myapp-abcde" }

   );
   console.log(app id: ${app.id})
   // process.exit() <- need to call this to actually finish running
   ```

2. Observe that node index.js never exits

This issue seems to have started happening in realm@10.2.0. Possibly related: https://github.com/realm/realm-js/issues/3525.

May be the real fix for https://github.com/realm/realm-js/issues/4530, in which case we can revert that change.
