This is v3 of the patch, with whitespace and comment changes as
requested by Carlos and Ondrej. I added comments marking the purpose
of atomic barriers and briefly explaining why we have forward
progress.
Curious if anyone has major objections they haven't voiced yet: what
more will it take to get this merged?
(Sorry about the long delay since v2; I've been buried with other bugs at work.)
