That sounds very sophisticated. I will try to see how far I can with the current approach and the latency it brings with it. You approach feels too much like doing the operating systems job, which is probably fine and necessary for your case. In my case the latency thing is just an annoyance that can be kept at bay with the easy approach with the background prio and I will rather waste some more brain cycles on other stuff like hunting application logic bugs ;-)
