*nix architecture is not real-time; it is queued, "best effort", pre-emptible. Real time is time-sliced, time budgeted,

Consider the computer on your unmanned mars-lander arriving at its destination. At precisely 3,000 meters above the surface of mars, it fires its retro rockets following the thrust profile, millisecond by millisecond. At precisely 1.1 meters above the surface it powers off the rockets.
There is essentially 0 time tolerance.

Ordinary *nix can not do this. I guess that fsmlabs has added hooks for high runtime priority, non-preemtible tasks and higher rate timing.
