Well, it's definitly not wrapped. I know because I had to work around
that. And it's definitly quite sick how I do this :)

I inherit from OFS.Folder.Folder, this should be enough, wouldn't it?
Especially Acquisition works quite well in all other methods, just not
__getattr__.

Well, I'm not getting hold of anything. It's more like Zope is getting
hold of my objects to publish.

As I've solved my problem (well, it works, I understand the problem, and
I know the correct solution, but I shying away of hacking Acquisition.
It's easier (for me) to get my wrapper from the Python frame stack than
to patch Acquisition.c.)
