I have in mind a solution which may work as a real fix, not just a
workaround. If it works out, it will probably make it into the 1.1.x
series first, but it should apply cleanly to 1.0.0. I'm pretty busy
with some other work right now so it'll be at least a few days before
I really get started on it I think.
