The rt_process.c and monitor.c comprise an example program that testsscheduling accuracy.  Execute "make test" or "run.sh" to run it. The Makefilecontains some insights.The programs in *irq*.c test interrupt response times of both Linux andRTLinux. You need two machines and a parallel cable to use it.To do: this should be documented in more detail. There's some infoin Michael Barabanov's thesis which can be found athttp://www.rtlinux.org/~baraban/thesis/
