As an alternative, would it make sense to try to understand why the
problems started when they did?  IOW, how come we never saw this until
now?

In http://debbugs.gnu.org/cgi/bugreport.cgi?bug=15583#23, Richard
provided the last good revno (113938) and the first bad one (114268);
I looked at that range of revisions, and 114156 looks relevant.  How
about if we revert it and see if the problems go away?
