Jack already posted results: the nice levels are massively inferior as they currently stand. The wrapper is incredibly inconvenient for applications: when you use JACK, start clients would require a different command depending on whether JACK is using RT mode or not. That is extremely inelegant, and its why we've developed these solutions (caps+jackstart for 2.4, "realtime" LSM for 2.6). --p - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
