Is this in reaction to this one?

>> 5)      Put multiple threads into a single measurement group

If we fix it to say "threads from the same CAT group" does it fix things?

We'd like to have measurement groups use a single RMID ... if we
allowed tasks from different CAT groups in the same measurement
group we wouldn't be able to split the numbers back to report the
right overall total for each of the CAT groups.
