I recommend looking at the code and trying to break it down into a bunch of
small, "obvious", incremental changes to the existing code. It's really
hard to review such a huge patch.

Not off the top of my head. You may want to ask on cfe-dev for the best way
to approach this.

Did you send the right patch? You don't seem to have addressed many of my
review comments. Please revisit my last message and make sure that you have
addressed those issues. There are numerous other changes I would like to
suggest but the ones I pointed out earlier need to be fixed before the
other changes can be meaningfully discussed.
