Hey Erik, Yes, background threads yet to terminate will cause the instance to remain standing, regardless of the idle timeout. I've just submitted a docs feedback which will hopefully see this fixed shortly in the "Modules in Python" docs page. You can, as Christian suggests, use the modules controls to manually turn-down an instance. I'm curious which Firebase library you're using, by the way, and how it uses background threads?
