    I would like to solicit comments on the following API for using CPU
    performance monitoring counters in FreeBSD.

    The intent is to use this API to support PAPI and other 'portable'
    performance monitoring libraries.

    The manual page is available here:

        http://people.freebsd.org/~jkoshy/download/pmc.3.txt

    A small tutorial on the API is available here:

        http://people.freebsd.org/~jkoshy/projects/perf-measurement/api-tutorial.html

    Code is being developed in our Perforce repository:
