In how many places have you posted about this issue?  This is the
third place where I see you trying to get people's attention.  What's
the urgency? :-)

I don't think the patch is ready yet, see my comment on SF.  If we
decide that anything needs to be done in this area I want to look at
it first, so please don't check anything in yet.
