Well, the implication was that QNX implements this as a kernel policy and that it's done automatically. A handful of drivers can be stopped and restarted, notably the network devices. The QNX filesystem resource managers and disk device drivers are notoriously finicky and aren't restartable in the general sense. Still, I like QNX a lot and have a major telecomm app widely deployed on it, going on five years in the field now. > However, as has been shown by the plethora of poor micro-kernel > implementations (QNX not withstanding), it's hard to implement a > well-designed/optimized micro-kernel, especially one that is not > architecture dependent.
