The future of realtime Linux in doubt

After contact with the hammer, the system ceases having the realtime property.

> So if you need a real-world system that meets latency specifications of some sort, you will need a somewhat more robust definition of "real time".

No, the realtime property is only guaranteed under a given set of conditions (correct hardware, stable power supply, lack of contact with a hammer). This is no different from e.g. a filesystem only guaranteeing consistency if the hardware doesn't lie about its buffers being flushed to stable hardware.
