This is all wrong in all possible ways :-( My excuse is the overnight
flight last night (no sleep). Mimi, I think what you first proposed as
the fix is the right way tho fix it. I'll take some sleep and after that
I'll make a legit commit with fix and a commit message explaining the
root cause.

Please try to ignore this.
