Linux Lennart Poettering of Red Hat, PulseAudio maintainer has blogged in detail about the impact of Real-Time Group scheduling in 2.6.25 kernel. The Real time patches come from -rt patchset maintained by Ingo Molnar of Red Hat which aims to make Linux the first general purpose operating system with hard real time features.

it's a well understood fact that hard realtime means guaranteed deadlines; unless the Linux kernel provides microsecond accuracy, it's "soft realtime".

You contradict yourself, here. If hard real time means guaranteed deadlines (and it does) what do "microseconds" have to do with it? The guarantee could be that it will definitely do something within one millisecond, or one year, but if it can be even one Planck Time over that, it fails the test. The definition of hard real time is, in fact, so pedantic, that I think I can say with reasonable certainty, that nobody, except maybe God, legitimately needs it.

In short, I think there's a Universal market of maybe 1 real time computer. And you can quote me on that. ;-)
