Please take a look at #2836 as an alternative. It is a much bigger patch,
but I think the refactoring it does will make things much easier longer term.
Having done the other patch I think this one does fix the immediate issue, but
the current HB cache is so complex that I didn't feel like I understood all of
the ways the cache was accessed before doing the other patch.---
