I am not knowledgeable of the granularity of timers under Linux. However, I headed a project which was a complex real-time data acquisition and control system. Data was acquired and a great deal of processing done it in a slice of time, which was limited by real-time contraints. It is in production use all over the Western Hemisphere. Linux works better than either of the other 2 unices that we've used for this task. This is accomplished to a large degree by a carefully designed priority schema. This combined with the POSIX real-time scheduling, which is in place, assures that the application processes will be executed in a timely fashion.
This may be something that you wish to consider in your judgement of Linux as a process control platform.
