This series is still not dividing up changes into small functional chunks. It
"ping pongs" (adding then later removing code), and makes it difficult to review
functional changes by surrounding them with non-functional transformations. As
I've attempted to break this apart myself, I've discovered a few issues with the
code - see the responses to the individual patches.

You can find my broken up version here:

In particular, please see:

Vadim, please respond to my questions re the individual patches, and I'll
increment the patches in the above branch before pushing this up to testing.
