There is no patch which we could revert to fix this, by Fujii Masao or
anyone else.  The patch he proposed has not been committed.  I am
still studying the problem to try to figure out where to go with it.
We could decide to punt the whole thing for 9.1, but I'd like to
understand what the options are before we make that decision.
