In case it isn't clear, I think that the proximate cause here may well
be either one (or both) of commits
efada2b8e920adfdf7418862e939925d2acd1b89 and/or
40dae7ec537c5619fc93ad602c62f37be786d161. Probably the latter. I think
that the profile is roughly consistent with that, although I may well
be wrong.
