I think a probability estimate is not all that exciting: "it's low
but not zero" is sufficient information to act on.  What I am curious
about is how come 86dc90056's changes triggered a visible problem.
Understanding that might give us a better feel for what is the real
structural issue here --- which I'm worried about because I have
little confidence that there aren't similar bugs lurking in other
code paths.
