What happens is that the memberof overlay, when stacked on the frontend
database, keeps looping until the stack is exhausted, since internal
modifications keep calling the frontend's modify hook rather than the
actual one that needs to be called.

I don't recall testing it this way during development, but I don't see any
reason to prevent it from working this way.  Feel free to look at it, I
probably won't have time to do it soon.

Thanks, p.
