Ok, that's fine. I don't have anything particularly scary lined up -
and quite frankly, despite the big numbers, this patch doesn't really
count as scary either - so right now I'm still planning to do final
3.16 this Sunday.

A pull request today or tomorrow sounds perfectly fine - a pull
request much closer to release less so.

Thanks,
