Thanks for the series.
I did a quick review highlighting some things that need to be changed.

Overall, the series seems to be in good shape. The tests went well.

In the next few days I'll see if I can get a better look at the larger 
patches like the tests, or I'll check in the next version.

Thanks,
Stefano
