We were rebuilding the checksummed file every time because redo-ifchange was incorrectly assuming that a child's changed_runid that's greater than my changed_runid means I'm dirty. But if my checked_runid is >= the child's checked_runid, then I'm clean, because my checksum didn't change. Clear as mud?
