What about the prior discussions on this list regarding the balance invariant 
not necessary being maintained during deletion?

There seemed to be a feeling that it would still work with a smaller balance 
factor.  Someone had also said they were going to work out a complete proof 
and post it somewhere.

I don't believe there has been any more followup though.
