The class-examples in CVS provide a couple of nice simple
examples of using these features.  Also rtmonuse is a nice
test which shows how to report the period statistics.

We would need RTEMS version information to provide more

interface for period statistics information was changed
to be more consistent with the rest of the Classic API.
