As soon as I get caught up on email, I'll be checking in some updates
that fix a bunch of issues. I don't know if it will fix this but
it could help. At any case it would get us to a common base line to
look at debugging this. The patch is attached and follows. It is
relative to -head. It should be easy to head and this to stable.
