Exams are long past, but there's a lot of other stuff -- the driver model, the
denx work, the LSM this week -- I wish I could cut myself in four or so.

But weren't there some open questions, especially about the function vs. command
stuff? The rest were really minor things and I believe you closed them with
ease. There are just the few big questions, but it doesn't seem people are too
interested to discuss them.
