After some thinking I found out that we cannot commit this patch until the memberof plugin is converted to use the new transaction interfaces for plugins, as otherwise it is possible to run into race conditions where the member/memberof relations are not settled if a new replica is installed while member attributes are being changed. Granted the race is quite small and unlikely but real. So please test and ack it, but we need to defer pushing to stable branches until ds copes. I think it is ok to push to master for testing, DS should have the necessary support by the time we make another stable release from master and in our test environments I am sure we will never hit the race.
