The operator returns "RUNNING_MODAL" when it starts, and then returns "FINISHED" when it's finished, but I'm not sure how to access that from another script.

I found this answer on blender.stackexchange which may help: https://blender.stackexchange.com/questions/143088/subscribe-to-finished-event-of-modal-operator-and-get-result-of-the-operator
