Sort of. That table “unrolls” groups. So you need to make sure that none
of the row’s children are still there either. We’ve got a fuller
explanation of the whole datamodel in our forthcoming O’Reilly book
"RT Essentials". But as Robert, Darren and I have been finding,
writing a book is slow going.

I can get more information about the datamodell? I just try
to avoid to read all the perl source code.
The CachedGroupMembers code should be some of the better commented code
in the source tree.
