after reading your question and following the discussion I too tried this out and found the same things. Only difference is I actually took an older project, applied the method to it and shook out some bugs I couldn't believe had not been caught. They were the kinds of things that people may have run accross and worked around (one definitely was according to one of the users who said they'd seen it), but it was absolutely frightening to think about how many bugs there actually were creeping around in something long considered "production".

seriousness one had as a child, at play." --Nietzsche
