Please review.

Thanks

Thanks for the reminding. I want the patch to go through Michael's vhost  
tree, that's why I don't put 'net' prefix. For next time, maybe I can  
use "vhost" as a prefix for classification?

The first parts, the get/put are in the hmm tree, and the last part,
the interval tree in the last commit is still a WIP, but it would
remove alot of that code from vhost as well.
