It was brought in by either

  Merge tag 'topic/atomic-core-2015-01-05'

or

  Merge tag 'topic/core-stuff-2014-12-19'

with the atomic stuff being the prime suspect (b46004b70367 is good,
so is 4b08eae52f2f and dafffda023b0).

The compiles should be going faster now that I'm getting closer, so
I'll have a tighter bisect soon. Knock wood.
