Hi Tim,

Thanks for the review, it was worth the wait :)
I recall thinking about this issue and convincing myself that it wasn't a problem, but I clearly don't know all the dark corners of this code.  Do you think it is reasonable to try to enumerate the cases where this estimation might go wrong (even conservatively) to avoid this problem?
