you can get NaN result. I've especially adjusted the code to get more of
less correct result in this case.
Hmm, good point. I think I managed to fix those cases in the attached
version. Is there any other corner case that I missed?
Did you try test case by Jeff Davis on this thread?

I try it with attached version of patch and get NaN estimate.
Thanks, fixed that too.
Committed with a little bit more clean up and fixes. Thank you for
bearing with this long process :-). And many thanks Jeff for the review,
and sorry that I forgot to credit you for that in the commit message.
