Did you miss the part of the folios discussion where we were talking about how
acrimonious it had gotten and why, and talking about (Chris Mason in particular)
writing design docs up front and how they'd been pretty successful in other

discussion what we're trying to do _before_ dumping thousands and thousands of
lines of refactoring patches on the list.
