Looks like when bio climbs from child group to parent group, then parent group slice starts fresh if parent was empty. So if we have a parent with 1MB/s limit and a child with 1MB/s limit and a bio gets queued in child, then looks like effective IO rate would be .5MB/s and not 1MB/s? IOW, when child gets queued, we should start time accounting for all parents in the hiearchy too.
