As you point out, we can't solve it in ELisp.  Note that this also
affects plain old `let` (for dynamically-scoped vars), tho the
time-window is shorter.

I think we could solve it by using `inhibit-quit` during `unbind_to`,
but that's a pretty significant change.  It might be The Right Thing to
do, tho.
