If it were extended in the future to include the ability to call at least `libperfstat_process` and `libperfstat_cpu` (in addition to `libperfstat_cpu_total`), then using it here would be a reasonable choice. There may be some other functionality required, but those stand out to me as the big ones.

Wouldn't adding the needed functionality to the existing libperfstat_aix 
be preferable here?
