Sadly not specifically - I did a semi-bisect looking at the suspicious
changesets back to the last successful test but have not find an
individual one which makes a significant difference.

As our 4.2 testing is quite new, it is possible it was just a fluke pass
before, meaning the range of "recent changes" might be anything in 4.2.
