Just my two cents ;)

No action on this bug in 4 months. I don't think It shouldn't be a release blocker either.

I think this one can be moved out as a release blocker. Too much debate and no action on the bug in over a month.

This would be nice to have, but is self-host in C++11 mode currently tested by the build bots?

A great bug to fix, but ARM is not a supported target for release criteria unless someone wants to make this happen for 3.3. So unless it gets fixed soon, it shouldn't block the release.

Dragonegg is a part of the release, but my question is.. is bootstrap only tested at release time (seems like some buildbots must test this)? This should be changed for 3.3. This seems like a more likely candidate to get fixed for 3.2 though.

Thanks for all your hard work with the release!
