Good catch, seems like that change was stripped out while I was cp-ing
from the internal tree. Some changes in this function have not been
promoted to Dave's branch yet.
I'll remove this comment for now, I think it makes sense to have a
follow-up patch to this after more changes have been promoted.
Thanks,
