Thank you for the report! This has been reported and discussed in a few different places on the mailing list with various solutions:

For the future, if you are able to bisect to the change that caused the failure, you can devise a more targeted Cc list and potentially find some of this information out beforehand, which would allow more threads to stay together.
The PowerPC build failure that you reported around the same time as this one has the same root cause.
Cheers, Nathan
