Indeed, I'd like to do that as time permits.  It's sort of an open-ended 
proposition though, because there are so many possibilities.  Deciding 
where to draw the line is tricky.  And for each example, to do it right, 
I'll have to write a mini-treatise on the pertinent assumptions and 

For me, the hard thing about writing is finding an appropriate stopping 
point - i.e. there is always more that could be said.  So I tend to 
avoid starting, because I know that the task will grow to fill all 
available time and then some.

For starters, I wanted to lay out the issues and the theory, so at least 
people start to realize that there is a possible problem.  From what 
I've seen, most people are currently totally unaware of it.

At least I did give one concrete recommendation - avoid reformatting if 
you can.
