I’m going to be unable to pay attention to Mercurial stuff during the freeze 
(probably the whole freeze? unsure) so it’d be helpful if others can make sure 
releases happen (including signing and cross-review).

I’m +0 on a freeze this time, to try and smoke out some real problems, as long 
as we also get that 5.8 pull regression fixed.
