Review Comment:
Ok. Let's do this later.
I agree with your comment. My idea was: When we inherit the counter value to
clones, the CFS problem is no problem as the CFS child inputs are opened early
and counter is zero at that time. But later clones on index files are opened
per thread or similar, so best is to inherit the counter.
