Ping!

We need to decide fairly soon whether to apply these (or perhaps just
patch 1 or just patches 2 and 3) for 4.9.  For any parts that aren't
applied, I'll send quick fixups to pin the stack in the offending
code.

I think we should apply it. Hopefully nothing uses it, and nobody will
notice. And if somebody *does* notice, the sooner we find out, the
better.

Ingo?  If we're going to make this change, I think it would be nice to
do it before -rc1.  If not, I want to get the alternate fix in ASAP.
