[PATCH RFC 0/7] Bug fixes and preparation for example hook

[Keller, Jacob E]

I am going to send a v2 of this series including the example hook I
referenced, as I have fixed several issues with this. In addition I
found some bugs with the current set of patches you pushed to devel, but
this series should clean them up too.

Thanks,
Jake
