I went through the patches, and it's a nice improvement, as well
as another good demo of the advantages of C++ over pure C.

For me, the patches look good. I should say, though, that my C++
knowledge is a little shaky, and there are probably better reviewers
out there itching to review this series ;-). The first 3-4 ones
are relatively straightforward for me. The last one is a little
more involved, but it looks reasonable and it makes sense to me.
