I don't think its clear that the query of death bug was included/fixed in the 8am GFS upgrade - they're just saying that an issue with similar external symptoms was recently fixed by upgrading to this newer version.
Sounds like the fact that this newer version was available was completely unrelated to this specific bug.
Yes, I understood that from reading the article, the point is that they still wasted an hour in trying to see if that would fix it or not because the symptoms were similar (crash of the master GFS server).
