Greg you are not going to back port all of these kobject fixes are you?
There is going to be a _lot_ of them.  I'm not super comfortable
generating all this work for you.  And besides that, I keep making
mistakes (reference to last nights find of double free in powerpc that
you reviewed already), then we have to back port those too.

For the record I've been going through all uses of kobject and splitting
them into categories

 1. Broken
 2. Too complex to immediately tell
 3. Done correctly

I'm not getting many in category #3, let's hope that some in #1 and #2 are
my misunderstanding and that many in #2 should be in #3.  I'm having fun
fixing them but I shudder at making life hard for other people.

Cheers,
Tobin.
