Those solutions raise the low-priority task to the higher circle. Which breaks a deadlock but doesn't fix the latency issue.

The low-priority task was low-priority for a reason. It wasn't supposed to soak up CPU cycles needed for higher-priority tasks. Those solutions do just that - making a long-running background task run before low-latency more-critical tasks increases their latency (delays them responding to their time-sensitive events).
