There's a bug in Zope 2.3.x regarding the method which changes ownership. 

This bug prevents Zope from changing ownership recursively if you already
own a branch, e.g.:

	FolderA
	|-- FolderB
            |--FolderC

If you don't own FolderC, but you own FolderB, then calling the change
ownership method recursively on FolderA will stop on FolderB because you
already own it. Of course you still don't own FolderC but it seems that ZC
people don't care.

It's possible this bug is still there in 2.4, I've not verified.

I've already submitted the one-line patch both to the defunct Collector
and IIRC to this list, as well as to zope-dev@zope.org, but to no avail,
so I'm sorry but you'll understand that I don't plan to submit it again.
