This is what I had started to do back in July of last year.  I was able
to fix some bugs while others I just filed for other people to fix.
Take a look at the meta-bug at .  It shows
all the known issues I was able to find with the patches attached.

I was the one who write the consistency checker but right now it is not
a separate pass (the patches for checker are in the meta-bug referenced
above) but it could easily moved to a separate pass.
