Don't do this...

My understanding (and I haven't invested much time into trying to
understand this beyond glancing at the change) is that patch 1 and 2,
introduce small bugs that are fixed in patch 3?

Just fold all three patches into one patch.  We need an Ack from Mauro
and Greg and then send the patch through Grant's tree.
