what is it? can you explain in comment

[David Trainor- moved to gerrit, 2015/10/15 22:18:02]

I wasn't sure either, but sync did it for their proto targets.  So I looked into
it and it seems to be used by a lot of places in Chromium to prevent exit time
destructors.  Added a comment.

[danakj, 2015/10/16 22:04:24]

But why is it important for the proto code? Is it? Why isn't it on everywhere in
cc? I'd like to understand..
