You were using? Or implementing?  Do you realize that these wern't actually
being used and wern't implemented correctly?

(BTW, One of the reasons for doing this cleanup is to set the stage for
  a decent savepoint implementation.)

I'm afraid it does.  ZODB is in a somewhat uniquely bad
state with regard to it's documentation and documented APIs.
As we can steal little chunks of time, Tim and I (and recently
Christian Theune) are trying to clean them up, but, as Tim says
you shouldn't pay much attention to them at the moment.  I
expect that in the not too distant future we'll be able to get
them to a place where they are actually useful.
