This function is a celery task but it seems like it is not being called correctly. The way it was, it would run in process. We update the call so that it is called asynchronously as a celery task instead. This may have some user facing impact as the work might now take longer to do than when it was running in the request process. However leaving it as is, definitely makes the user experience slower causes us to do computationally intensive work in the web request. It also makes it much harder to monitor as our ownership assignment tracking for the feature does not work correctly.
