   - If ``poolOptions`` is specified, use those options to initialize both pools
   - The returned pool must have an ``address`` set as a string value.
-  - If the pool uses a background thread to satisfy ``minPoolSize``, ensure it
-    attempts to create a new connection every 50ms.
 
 - Process each ``operation`` in ``operations`` (on the main thread)
