Periodic thread with Linux

[Jack Cawkwell]

This cannot be done under normal Linux. Linux is not real-time,
so you cannot guarantee that the process or thread will be
able to be scheduled to run at the time required. There are
systems that use Linux combined with some real-time support,
you may like to look at these if you want to have Linux and
a small amount of real-time processing.
