Hi Theodore and thanks for the interesting analysis.

If Zdenek doesn't jump in to further clarify the issue during the next 
24-48 hours
or so, I would suggest definitely filing a PR, including at least a 
summary of your
analysis. If you are not able to do that, please let me know and I will.

Thanks again,
Paolo.
