I agree.  One thing that should be done for the merge is getting rid
of ->prepare_write and ->commit_write.  Historic data show that if 
we start a partial transition it will take ages to finish it.  In addition
to that the backwards compatibility code in this case is rather big and
very ugly, and we'd be better off without it.
