 - Generally real-time processes need to communicate with other non real-time processes. **Do not use standard mutexes (e.g. `std::mutex`) when communicating between threads with different priorities** as this is known to potentially result in [priority inversion](https://en.wikipedia.org/wiki/Priority_inversion): A low-priority task might only run after another task with same or slightly higher priority and therefore block the high-priority task that relies on the low-priority task to complete
