A couple of days having gone by without hearing further on this, I'm
going to assume for the moment that my analysis is correct and just
push a commit to remove this assertion. That's not intended to
discourage you from spending further time on this - it would be bad to
be wrong about this - but doing something we all agree is wrong can't
be better than doing something that I, at least, think is correct.
