Right now, if the result is a single document with error, the application callback is called directly. This means that if the application code throws an exception, it gets propagated to the driver code causing unexpected behavior (server topology being destroyed in my case).
Using
handleCallbackensures that in this scenario, the exception does not get propagated to the driver code.
