Seems like a phrase was about to be replaced with another one, but only the addition made it in, not the removal.

I agree with what you're trying to do here but it is still not technically correct. The integer doesn't point to the number. It would probably be better understood if we were colloquial like 'running_handles receives the number of running easy handles' or something simple like that.

Thanks, it landed as: "At return, running_handles points to the number of running easy handles within the multi handle."
